FloMASTER Release Highlights, V9.2.0 1 February 2019


Introduction This document provides a high-level summary of the FloMASTER® V9.2 release. It includes a summary of the new features in this release, authorization code changes required, any major installation changes, and transitioning issues you should be aware of before installing. Additionally, any last minute issues found in the final stages of testing are included.

New Features The following new features are available in this release.

Connectivity CAD2FM Enhancements

FloMASTER V9.0 introduced CAD2FM offering significant advancements in productivity through automated connectivity to 3D CAD design tools. The new “CAD-to-FloMASTER” (CAD2FM) functionality enables design engineers to rapidly create System representations of their 3D systems. CAD2FM automatically abstracts the 3D descriptions of piping networks into a collection of connected FloMASTER components, reducing manual, labor-intensive and error-prone measure and re-enter methods

In addition to the geometric data that can be used for the specification of diameters and lengths the 3D description also contains the elevations of the points that the elements join at. In FloMASTER V9.2 CAD2FM has been enhanced by exporting the elevation of nodes connecting components in addition to the geometric data. This allows the effects of changes in level at the nodes to be captured automatically without the measure and re-enter step. In the resulting simulation the change in level will be reflected in the calculation and results.

Portable OneSim

‘OneSim’ introduced in FloMASTER 9.1 is a tightly coupled co-simulation workflow that enables a FloEFD model to be considered as part of a FloMASTER network. A OneSim file is exported from a loaded FloEFD model. On import into FloMASTER, a 3D preview of the FloEFD model geometry enables one or more FloEFD hydrodynamic boundary conditions to be nominated for linking to the FloMASTER network. A OneSim N-Arm component is created and, once connected to the FloMASTER network, a simulation instigated from within FloMASTER will solve both the FloEFD model and the FloMASTER network concurrently, until steady state or transient convergence. Flow rates, pressures and fluid temperatures will be communicated through the linked boundary conditions/ hydraulic nodes throughout the solution process. In addition one or more FloEFD Goals can be exposed as OneSim N-Arm output signals.

Such a workflow enables the accuracy of a 3D CFD simulation to be applied to parts that would otherwise be overly simplified when represented as 1D components.

At FloMASTER V9.2 OneSim the user has the ability to change the location of the FloEFD model allowing the model to be run on a different machine rather than being tied to the model that the models generated on.



User Experience A positive User Experience (UX) is always obvious by its absence. However, its importance is often overlooked: it’s intrinsically linked to the cost of ownership of a product, affecting both user confidence and the time taken to achieve a goal.

Post Processing After a simulation post processing tools can help in understanding the results of a simulation in ways that may not be apparent from the raw numeric results when viewed on a component by component level. In FloMASTER V9.2 new post-processing tools have been added to FloMASTER with updated network result display, enhancements to dashboards and new reports. To aid in finding these tools and improve access to existing ones a new post-processing toolbar has been added with one click access to the tools.

The Post Processing toolbar provides access to the following tools;

• Network Result Display • Results Dashboards • Thermodynamic Cycle Diagrams • Pipeline Profile • Steady State Result Report

Network Result Display

The Network Result Display provides a 3D CFD-like experience and allows the quick visualization of component arm, node and internal pipe results on the schematic aiding a quick understanding of system wide variables.

It’s possible to view the magnitude and where appropriate direction of the result in three ways:

• Line Thickness

• Line Color

• Arrows indication direction

Custom ranges can be set for the values and the three options independently toggled on and off.

For a transient simulation the results can be played through time allowing the user to see how results change with time across the system

Dashboard & Reporting Enhancements

Dashboards were introduced in FloMASTER V9.0 and allow the user to add the results that they are interested in to a canvas that can be saved. Once saved it can be used to view the results from any simulation the user has run for the system.

Figure 3 - Dashboard For Rising Main System

In FloMASTER V9.2 Dashboard’s have been enhanced as follows

• The dashboard can now be access from the Post-Processing toolbar

• The dashboard definition is now saved to the network in the database

• If a network is copied with a dashboard then the copy will also have the dashboard

• The dashboard will be packed with the network

• The results from the dashboard can be directly exported to Excel for further post processing.

When combined these features significantly enhance the dashboard allowing portability between networks and users while also providing a template for transient result output.

Hydrodynamic Force Export

The Hydrodynamic Force Export has been enhanced to allow the export of results to Rohr2 without an associated mapping schema

Enhanced Steady State Report

FloMASTER V9.2 introduces a new report for steady state report. The report includes:

• Component ID, Component Type and the value (if set) of the component Group, Type and Title Fields

• Branch Results for each component arm and the node results associated with that arm

• All component internal results

Figure 6 - Steady State Result Report

The report can be customized with user control over fields shown, filters on results and custom sort orders and the layout then saved to the database for future reuse. The result contents can also be exported directly to Microsoft Excel for further processing if required.



Connectivity

In FloMASTER V9.2 the connectivity rules for signals and measurements have been changed. This means that signals and measurements can be mixed when connecting control systems with less requirements for gauges to be added.

Sample Systems

FloMASTER V9.2 adds 4 new sample systems taking the total available to 26.

Figure 8 - New Sample System Images

The new sample systems are;

• Unsteady Friction

• Steam Power Plant

• Visual Programming

• Super Critical CO2 Power Generation



Physics Gas Turbine Secondary Air Modelling

FloMASTER V9.2 includes two enhancements to FloMASTER’s modelling of secondary air systems in gas turbine engines

Gas Turbine Internal Duct

The Internal Duct component is intended to model rectangular channels with enhanced surfaces. These types of flow passage are commonly encountered in the cooling passages of turbo-machinery such as gas turbines. The component can be used to model flow passages in both the rotor and stator elements of turbo-machinery.

Rectangular ducts of variable cross-sectional area with up to four different types of enhanced surface around the duct wall can be modelled. The duct can be specified to rotate about an axis and the rotational enhancements to friction and heat transfer are considered.

Figure 9 - Temperature Distribution through Internal Ducts in Turbine Blade

Although ducts with smooth walls can be modelled the component is primarily intended to model friction and heat transfer at enhanced surfaces.

In FloMASTER V9.2 the duct has been updated providing an easy to use data form and allowing the user to enter friction and heat transfer correlations using scripts stored in the FloMASTER database for future reuse.



Gas Turbine Vortex Components

Early in the design of a secondary air system full cavity geometry may not be available. FloMASTER V9.2 adds the following components to allow the rotational effects of a cavity to be modelled at an early stage with minimal data.

• Forced Vortex 2-Arm

• Free Vortex 2-Arm



Further Physics Enhancements

Handling of Humidity over 100 %

In FloMASTER V9.2 the ability to model fluid streams of air with humidity has been extended. In earlier versions fluid properties would be considered upto 100% relative humidity but did not include the effects of condensation once the saturation point was reached. In FloMASTER V9.2 the fluid properties are calculated for the saturated air. In addition the following models have been updated to include the effects of condensation and evaporation as the stream crosses the saturation point

• Turbine

• Compressor

• Heat Exchanger: Heater-Cooler

• Heat-Exchanger: Thermal

Iteration Viewer

The Iteration Viewer allows the user to quickly view the steady state convergence behavior of a result, this can be useful in debugging systems that fail to converge. The Iteration viewer can be connected to component arms, nodes and result outputs

Lower Order Battery Model

Following the release of the 2nd order non-linear equivalent circuit battery model in version 9.1, additional modeling options have been added to work with already existing parameter data. These include along with their data requirement:

- Rint Model: R0



- Thevian Model: R0, R1, C1

- Dual Polarity Model: R0, R1, C1, R2, C2

Each model is available as part of the battery component in FloMASTER and corresponding model is selected at run time based on the data entered.
