Chair’s Message by James A. Liburdy, Ph.D. Dear FED Members, I am pleased to be writing to all of the Fluids Engineering Division members to report on some new and exciting activities within the division. Our goal is to help improve member participation by making it a rewarding and produc- tive part of your professional activi- ties. Currently the FED has approx- imately 3500 members with another 4200 identified as sec- ondary division members. We also would like to continue to reach out to potentially new members to broaden out impact, to become the premier professional society for those working in the broad areas of fluid mechanics. To this end we encour- age your comments and ideas as we move forward. This past summer we had a rather unique event, a collocat- ed conference with the Heat Transfer Division, the Advanced Energy Division, and the Nanotechnology Institute, located in Jacksonville, FL. The meeting was organized to allow partici- pants to attend sessions sponsored by each division, and papers from each conference were available for all who regis- tered for any of the individual conferences. This event brought together people working in diverse yet highly overlapping areas and hopefully spawned many contacts and potential col- laborations for the future. The conference attracted over 750 paid attendees with a truly international flair. Each conference had two plenary speakers, for a total of eight. For FED Dr. William K. George of Chalmers University was awarded the Freeman Scholar and presented a lecture on the effects of ini- tial and upstream conditions on turbulence shear flows, and Stuart Jessup provided an historical perspective of Naval propulsor design. The FED is an active participant in the ASME IMECE con- ference held each November, and last year, in Boston, IMECE 2008 was no exception. At Boston, FED organized twelve dif- ferent symposia or fora. Since this conference is organized into major Tracks, FED participated in seven different tracks, ranging from Heat Transfer, Fluid Flows and Thermal Systems, to Energy Systems, Emerging Technologies and others. The more technically oriented IMECE, compared with the past, includes a wide range of technical events and again provides a great opportunity for those involved in fluid mechanics to engage with other disciplines. In addition, IMECE is where FED holds its Young Engineer Paper Contest, which has been spearheaded by Dr. Terry Beck over the last several years. This has turned into a truly international event, with competi- tors from around the global coming to participate. This con- test is based on submitted papers by undergraduate or early graduate students. The papers can be part of a team project or have single authors.

    Fluid Measurement and Instrumentation Technical Committee

    Theodore (Ted) J. Heindel,Ph.D., FMITC Chair

    The Fluids Measurementand InstrumentationTechnical Committee(FMITC) is the ASME Flu-ids Engineering Divisioncommittee devoted tomeasurement techniquesand their application to

    fluid flows. The scope of the committee’sgoals include both experimental techniquedevelopment and application in academiaand industry. The primary activity of theFMITC includes development and organiza-tion of technical sessions at the FluidsEngineering Division summer meetings andthe fall IMECE meetings. Since fluid meas-urements are common to all experimental-ist, the FMITC also collaborates with otherFED technical committees in co-sponsoringtechnical sessions. The committee’s mem-bership represents a broad spectrum ofbackgrounds, including industry, govern-ment laboratories, and academia. Thetypes of measurements and instrumenta-tion include those applicable to subsonicand supersonic flows, multiphase flows,large-scale flows, microfluidic flows, andmany others. The FMITC goal is to be atthe forefront of new measurement tech-niques and to provide a forum to exchangemeasurement and instrumentation ideas,developments, and applications.

    The FMITC meets at the ASME FEDSummer Meeting and at the ASME IMECEmeeting. Non-members from students toseasoned professionals are encouraged toattend these meetings, which areannounced in the respective conferenceprogram. We are continually looking fornew members to assist in, as well asdevelop new, technical sessions address-ing measurement and instrumentationissues. We also encourage those fromother ASME divisions and technical com-mittees to attend to develop collaborativetechnical sessions which extend the appli-cations of fluid flow measurement andinstrumentation to other disciplines, suchas heat transfer, bioengineering, energysystems, etc. Examples of recent technicalsessions sponsored or co-sponsored bythe FMITC include: Forum on Fluid Mea-surement Uncertainty Application, Panelon CFD/EFD Choice – A Dilemma forIndustries, Symposium on Non-InvasiveMeasurements in Single and MultiphaseFlow, Forum on Fluid Measurements andInstrumentation, and Forum on Automo-tive Flows.

    If you have any questions or sugges-tions for the FMITC, please contact thechair, Ted Heindel at [email protected],or the vice-chair, Pavlos Vlachos at [email protected]. �

    Computational Fluid DynamicsTechnical Committee (CFDTC)

    Richard W. Johnson, PEChair, CFDTC, IdahoNational Laboratory

    This summer at the2009 FEDSM in Vail,Colorado, the CFDTC willhost its historically impor-tant symposia on newCFD algorithms, new andtraditional turbulence

    modeling approaches, fluid-structure inter-action and flow-induced noise and generalCFD applications. In addition, CFDTC joinsFMTC in hosting a symposium on verifica-tion and validation in CFD. In conjunctionwith the V&V symposium, the CFDTC hasinvited Dr. Bill Oberkampf to present a ple-nary talk at the FEDSM addressing thisvery issue.

    While we may view the historical areasof CFD interest as being the most fun towork with, as engineers, we must alsoengage ourselves in the perhaps not soexciting task of qualifying our CFD simu-lations for the benefit of the recipient oruser of those calculations. We need to ver-ify our CFD coding, verify our calculationsand validate our calculations. We all knowthat anybody who can run a computerapplication and click on options can pro-duce a “CFD simulation.” But how good isthat simulation? Has it been processedthrough the various procedures that weknow to be basic to its acceptability? Arewe conversant with the terminology thathas come to be generally accepted in theV&V community. How about our manage-ment? Do they know what is required toqualify a CFD calculation?

    There are a number of subjects relatingto the practice of V&V that can actually bequite deep and may strain our intellectualcapacities. For instance, we would like tobe able to quantify the numerical uncertain-ty of the calculation. How do we do that? Isthere more than one way? Do we have touse 2 or more grids to do it? Also, there isa need for a quality database of experimen-tal data that can be accessed by CFD prac-titioners whose contents is comprised ofvalidation data sets that are complete andalso have a qualification pedigree, especial-ly a good uncertainty analysis. When wethen attempt to use data from the valida-tion database, we need to do better thanprovide the usual “viewgraph” norm com-

    parison. That is, there should be one ormore procedures that produce some kindof numerical metric such as a confidenceinterval that quantifies the simulation ver-sus the data. Many of these procedures arestill subjects of research and improvement.You should become acquainted with themand their genesis.

    If we want the (engineering) world toaccept our CFD magic as reliable approxi-mations of reality, we have to provide thepedigree or list of quality assessments thathave been performed to qualify it. We mustbe conversant with the terminology and theprocedures that comprise it. In manyregards, CFD is a mature engineering sci-ence, though we hope to be able to contin-ually improve on existing techniques. Butwe must also certify our work to our cus-tomers so that its full power can be takenadvantage of and appreciated.

    We invite all to attend the plenary talkby Dr. Oberkampf who is an acknowledgedexpert in V&V and has served on a numberof task forces to develop and codify V&Vpractices and procedures. He is also in theprocess of co-authoring a book on V&Vpractices. We also invite you to participatein future V&V symposia we hope to hold atfuture FED summer meetings. �

    Fluid Applications and SystemsTechnical Committee (FASTC)

    S. A. Sherif, Ph.D., Chair& D. Keith Walters, Ph.D., Vice-ChairFASTC, Fluids Engineering Division

    The Fluids Applications and SystemsTechnical Committee (FASTC) continueto promote the advancement and dissemi-nation of fluids engineering research andtechnologies in several wide-ranging single-and multi-disciplinary topic areas. Theseinclude such traditional disciplines as fluidpower systems, turbomachinery, automo-tive flows, and industrial and environmentalfluid mechanics, and can include less tradi-tional topics such as biological and bio-medical systems, chemical processing, orfluid vibrations and acoustics. The primaryfunction of the committee is to coordinateand organize research symposia at twomajor venues for fluids engineering—theannual ASME Fluids Engineering DivisionSummer Meeting (FEDSM) and the ASMEInternational Mechanical Engineering Con-gress and Exposition (IMECE)—as well asother FED sponsored meetings and events.Researchers and engineers from academia,industry and government are encouragedto meet and exchange information on theseand other topics through their participationin FASTC.

    Fluid Mechanics Technical Committee (FMTC)

    Francine Battaglia, Chair& Javid Bayandor, Vice-Chair

    The Fluid MechanicsTechnical Committee isdedicated to organizingand promoting technicalactivities within ASMErelated to fluid mechan-ics. Members of the

    FMTC volunteer their serves to develop,organize and promote symposia and paneldiscussions on fundamental and contem-porary topics relevant to the researchcommunity. Often, these platforms areheld twice per year at the InternationalMechanical Engineering Congress &Exposition (IMECE) and Fluids Engineer-ing Division (FED) Summer Meeting.

    The FMTC is pleased to announce thatProf. Mory Gharib, the Hans W. LiepmannProfessor of Aeronautics and Professor of Bioengineering at Caltech, will be a plenary speaker at the 2009 Fluids Engineering Division Summer Meeting to be held in Vail, CO this August. For further information about the meeting and plenary speakers, please visitwww.asmeconferences.org/FEDSM09/

    To coincide with the annual confer-ences, the FMTC holds a business meet-ing at the IMECE and FED events. Elec-tion of the FMTC officers was held at the2008 FED Summer Meeting in Jack-sonville, FL, after which the officers servea two-year term (2008-2010). During thebusiness meeting held at the 2008 IMECEin Boston, MA, the FMTC memberspassed a motion to allow only two formattypes when authors submit abstracts formeeting presentations. Beginning withthe 2009 IMECE, authors will have theoption of either submitting a full technicalpaper for presentation, which will also bereviewed and published in the proceed-ings, or giving a presentation only(abstract but no paper). We hope theseoptions will promote and encourage moreauthor participation in the sessions spon-sored by the FMTC.

    During the last few years, we havewatched the membership of the FMTCgrow to include involvement from gradu-ate students, postdoctoral research associ-ates, and junior faculty members. Theinfusion of new members helps the FMTCsustain our professional activities. Withoutthe support and dedication of the FMTCmembers, we would not be able to offerthe variety of technical sessions held atthe annual conferences.

    IntroductionUnwanted dispersed matter (dust or

    droplets) in industrial vapor streams is acommon problem. Cyclones, havingrelatively low costs of construction andoperation, have been used since the late1800s to separate these phases. Parti-cle-laden gas enters through an inlet,swirls in a free vortex around the bulk ofthe unit, and proceeds into the forcedvortex before exiting the top of the unit.Particle-rich gas leaves the bottom intoa dust bin or other collection system. Inthe present work a Lappel cyclone cou-pled with an annular ejector is used toremove polyethylene dust from a densegas stream. The goal is to optimize thesystem within strict geometric and oper-ating constraints.

    ModelFigure 1 shows the overall layout of

    the present work. A multitude of meshblocks is used to minimize mesh spacingin areas of high gradients, cell skewness,cell aspect ratio, and cell centroid shifts.The grid size ranged from 570,000 to740,000 cells, the vast majority of whichare hexahedra. Two-equation turbulencemodels cannot account for couplingamong the Reynolds-stress tensor com-ponents, concave surface turbulenceenhancement, or counter gradient diffu-sion physics; therefore, a differentialReynolds Stress Model (RSM) solutionwill be sought. Mach numbers are signif-icant in the present study, so compress-ibility, viscous heating, pressure work,and the kinetic energy terms wereresolved. The dispersed phase isapproached using a Lagrangian stochas-tic discrete random walk (DRW) method[1]. A commercially available pressure-based, 64-bit, finite volume, double pre-cision code, Fluent 6.3.26, was used tosolve the equations governing momen-tum, heat, and turbulence in both phasesin space and time. The convective termsof the momentum equations were dis-cretized using a QUICK scheme. Atimestep size and sub-iteration countwere chosen such that RMS residual“flattening” (continuity of order 10-5)was achieved and the instantaneousmass imbalances were less than +/- 1%.Each run proceeded in two stages: 1)

    development of statistically stationary(quasi-steady) flow and 2) time-aver-aged data collection. To help decidewhat exactly represents “enough” timefor the first stage, 22 values, such as tur-bulence kinetic energy and Mach num-ber, were monitored during the runs.

    Flow FeaturesFigure 2 offers typical instantaneous

    contours of tangential velocity, tempera-ture, and dust concentration. Anexpected strong swirling motion is seenwith an asymmetric approach to thelower outlet [2]. Hot vapor is fed to theinlet, and hot motive fluid is fed to theejector. Gas expan-sion lowers the tem-perature in the cen-ter of the cyclone.The clean (upper)outlet is relativelywarm and is likely acombined effect ofstrong radial turbu-lent thermal diffu-sion near the vortexfinder [3] andbypassing of thefeed flow to the vor-tex finder. The par-ticle concentrationcontours show anexpected increasein concentrationnear the walls of thecyclone and vortex

    finder. There are also interior lobes ofhigher concentration dropping down tothe lower part of the straight cyclonesection, and some particles (entrain-ment) are seen making their way backup the center in the return vortex.Notice also the relatively high concen-tration of particles just under the vortexfinder. Bypassing appears to be thedominant mechanism for particle carry-over. The particle concentration contourshapes, especially the interior “bands”,change dramatically in time. The quasi-steady behavior is exemplified in Figure3, showing a typical time series plot ofthe overall system separation efficiency.

    Figure 4a shows instantaneousLagrangian particle tracks released fromthe cyclone inlet colored by residencetime. Particle concentration helical stri-ations are seen forming in the cyclone([2], [4]). There is evidence of strongbypassing of the particles under the vor-tex finder. The shades of blue (low resi-dence time) proceeding vertically out ofthe clean top indicate a short period oftime that particles are in the unit.Bypassing is further explored in Figure4b. Here, the continuous phase istraced by residence time moving inreverse from the clean outlet. Shades ofblue (low residence time) are seen invarious positions in the inlet. Anotherinteresting feature is the particles caughtin the secondary flows shown in red(long times) near the cyclone roof dis-cussed in [2]. Typical instantaneoustangential velocity contours on an ejec-tor midplane are shown in Figure 5.Three uncorrelated time steps have beensampled to show the unsteady nature ofthe flow. Rings of helical flow are shedas the vorticity of the swirling cycloneflow re-orients upon meeting the high-speed ejector motive steam. It can be

    seen that the effects of the cyclone arechaotically felt deep in the ejector. Itwas found that the state of the flow exit-ing the cyclone bottom affected themotive feed pressure balance. The pres-sure balance controls the ejectorthroughput. In turn, the amount ofmaterial ejected impacts the solids car-ryover rate. The two units could, there-fore, not be separated computationally.

    ConclusionsThe complete work can be found in

    [5]. Six geometric configurations forimproving the solids collection efficiencyof a joint cyclone separator / ejectorhave been evaluated using an unsteady,compressible DRW with RSM approachin a commercial code, Fluent 6.3.26.Significant effort was placed on ensuringa converged solution with statisticallysound data collection and time-averag-ing. It was found that an extended con-vergent vortex finder had the greatestimprovement in particle collection, whilethe pressure drop increased markedly asexpected. Two sizes of simple disk-shaped vortex breakers showed noimprovement, while an extended vortexfinder with a fixed diameter showed adecline in performance. A dust bin

    showed a very slight improvement, butthe dust bin was a non-ideal design dic-tated by process space limitations. Allparticle collection directional changeswere marginal. Solids collection did notnecessarily correlate with tangential flowin the downpipe or ejector throughput.More work is planned to evaluate vari-ants of these designs and others. Inaddition to six geometry evaluations,four numerical effects were considered:pressure-velocity coupling, pressure dis-cretization, RSM pressure strain formula-tion, and wall reflection. Minor effectswere found by changing from the linearto quadratic formulation. Almost noeffect was seen when the pressure-velocity relations was handled in a cou-pled or SIMPLE approach. Very largechanges were seen by choices for pres-sure discretization and the inclusion ofwall reflection terms. It was concludedthat a PRESTO! scheme and the linearpressure strain approach with no wallreflection are the most accurate and effi-cient approaches.

    Unified Two-Phase CFD Modeling of Boiling, Cavitation, and Bubble CollapseRay A. Berrya, Richard Saurelb, Fabien Petitpasb

    Keyissues in nuclear reactor safetyand optimization rely on in-depthunderstanding of basic two-phase flowphenomena with heat transfer and phasechange. Among these issues, convectiveboiling under normal and elevated pres-sure conditions is one of the most chal-lenging situations. Our inability to accu-rately predict heat transfer and associat-ed boiling fluid topology transitions fortwo-phase flows under nuclear reactorflow conditions and fuel bundle geome-tries results in increased safety marginswhich impedes development of new fueldesigns. With the advent of new genera-tion codes and the increase of availablecomputational power, it is believed (asevidenced at the recent international“Two-Phase Convective Boiling FlowModelling” workshop [1]) that significantprogress can be made by using special-ized computational fluid dynamics(CFD) codes, thus leading to a drasticreduction in development costs. InEurope, and especially France, CEA,EDF, AREVA and IRSN have launched,among several projects covering a broadspectrum of space and time scales, theNEPTUNE [2] project, aimed at provid-ing computational tools describing two-phase flow and heat transfer that arevalidated in the parameter range ofindustrial applications. In the UnitedStates no such unified effort exists; how-ever, it seems necessary to promote col-laborative research on this subject at thewidest scale. A collaborative effortbetween the Multiphysics MethodsGroup at Idaho National Laboratory(INL) and the SMASH Team at ÉcolePolytechnique Universitaire de Marseillehas recently begun to pursue theseissues through development of a unifiedapproach [3]. This short research notehighlights one component of the broaderdevelopmental effort [3].

    The purpose of this research is todevelop the foundations needed tosimultaneously solve both fluid dynamicinterface problems and multiphase mix-tures problems arising from boiling, cavi-tation, and bubble collapse in light waterreactor systems. The two-phase flow

    phenomena occurring in light waternuclear reactors includes, especially withdeparture from nucleate boiling (DNB)and film boiling instability (boiling crisis),coolant phase changes and multiple flowregimes that directly influence coolantinteraction with the fuel elements andassemblies, ultimately affecting reactorperformance. Because of the inherentcoupling, an understanding of these phe-monena, along with subcooled boilingand bubble collapse, is also key to gain-ing an understanding of crud depostionin these systems. Our goal is to provideunified models giving highly resolvedsolution details where necessary, simul-taneously with lower resolution, large-scale vessel/component solutions. Thiswill be accomplished through the develo-ment of a well-posed, multiscale methodthat (1) resolves interfaces for largerbubbles with single velocity, single pres-sure treatment in a DNS-like (directnumerical simulation) manner using afine computational mesh, and (2) aver-ages (or homogenizes) the two-phaseflow field for smaller bubbles, yielding atwo-velocity two-pressure treatment,using a courser computational mesh.

    Multiphase formulations have beendeveloped to provide the ability to solveproblems involving both heterogeneousmixtures of materials and interfacialflows involving compressibility withphase transition. In particular, for theDNS of interfacial flows which are ofprime importance for nuclear reactordesign optimization and safety analysis,the aim is to compute the critical heatflux conditions that involve a competi-tion between bubble growth, surface ten-sion, contact angle effects, and heat andmass transfers at interfaces. Contrary tothe approach developed by otherresearchers, such as sharp interfacetracking methods, our approachembraces a general model that accountsfor complete thermodynamics in bothphases. Because of the inherent weak-nesses of sharp interface methods forDNS-like simulations, most notably theirinability to dynamically create interfacesand to solve interfaces separating pure

    media and mixtures, we focused on adiffuse interface method (DIM) whichdoes not exhibit these weaknesses. DIMconsiders interfaces as numerically dif-fused zones corresponding to artificialmixtures created by numerical diffusion.The determination of thermodynamicflow variables in these zones is achievedon the basis of multiphase flow theory.The challenge is to derive physically,mathematically, and numerically consis-tent thermodynamic relations for theartificial mixture. The same solutionmethod is implemented globally in bothpure fluids and in mixture zones. For thisresearch the numerical approximation ofthe five-equation, two-phase flow modelof Kapila (zero-order approximation ofthe seven-equation model with stiffrelaxation) [4], which has shown excel-lent capabilities for numerical resolutionof interfaces separating compressiblefluids and wave propagation in com-pressible mixtures, was examined. Forseveral reasons, its numerical approxi-mation poses serious difficulties. In ourwork, these difficulties were circumvent-ed by restoring pressure non-equilibriumeffects using a pressure non-equilibriummodel developed in [5]. This resulted ina single velocity, non-conservativehyperbolic model with two energy equa-tions involving relaxation terms; it fulfillsthe equation of state and energy conser-vation on both sides of interfaces andguarantees correct transmission of pres-sure waves across them. This formula-tion considerably simplifies numericalresolution by building a simple and effi-cient method for numerical approxima-tion of this flow model in the context ofdiffuse interfaces. Further details of themethod and results are given in [5].

    To demonstrate the multidimensionalcapability, a two-dimensional test,involving a Richtmyer-Meshkov instabil-itly (RMI), is presented from [5]. The liq-uid is not pure and new interfaces willappear during development of the insta-bility due to cavitation effects. Theshape of the resulting interface and theentire flow field show a non-conventionalbehavior, never computed before, as themodel and method must deal with liq-

    uid-gas interfaces and the dynam-ic appearance of gas pockets insevere conditions. The physicaldomain is 3 m long and 1 m high,with the left part of the computa-tional domain filled with nearlypure water and the right part withnearly pure gas. They are initiallyseparated by a curved interface, aportion of a circle with 0.6-mradius centered at x=1.2 m, y=0.5m. The mesh contains 900 cells inthe x-direction and 400 cells in they-direction. Both water and gashave an initial pressure of 1atmoshere and an initial velocityof -200 m/s (to the left). The ini-tial density of water and gas is1000 kg/m3 and 100 kg/m3,respectively. Top, bottom, and leftboundaries are treated as solidwalls; right boundary is open. Bothphases are treated with the stiff-ened gas equation of state [6];therefore, both phases areassumed compressible. The waterin the left part contains a verysmall volume fraction of gas, 10–6,while the gas in the right part con-tains a very small volume fractionof water, 10–6. The initial configu-ration is shown in the uppergraphic of Figure 1, and the mix-ture density contours at times 0.0,1.9, 3.9, 5.8, and 7.8 ms in theother graphics of the figure. Whenflow impacts the left wall, a right-traveling wave propagates in thedomain through the water/gas dis-continuity. A conventional RMIappears first. Then expansionwaves are produced as the jetelongates. It results in expandedzones near the solid boundarywhere gas inhomogeneities grow,producing the dynamic appear-ance of gas pockets (white) andinterfaces. Because the pressure isvery low in these zones, the jet’sdynamics are modifed from theconventional RMI in pure fluids. The var-ious gas pockets near the solid bound-ary and in the jet core are clearly visiblein Figure 1. Relaxation terms present inthe volume fraction and energy equa-tions are responsible for the dynamicappearance of these gas pockets. Thiswould be very difficult to accomplishwith current sharp interface trackingmethods.

    By incorporation of interfacial surfacetension and heat and mass transfereffects, this simple, efficient and robustmethod can be used to resolve fundamen-tal boiling issues in a DNS-like mannersimilar to the cavitation example above.Furthermore, the various componentsemployed in this method are generalenough to merit coupling with additionalcomplex physics and chemistry, e.g. toaddress the unwanted deposit of con-

    stituents dissolved in the coolant asa result of localized boiling — the so-called crud deposition problem.
