We sincerely thank our sponsors and organizersLocal organizationTetsuya Aizawa (Meiji Univ.) and Hiroshi Kawanabe (Kyoto Univ.) and staffTechnical session organization

You (and your sponsor)! Your participation and expert analysis, most of it during many weeks of volunteer time before this meeting, will make the workshop worthwhile Diesel nozzle geometry and internal nozzle flow, Marco Arienti (Sandia) Primary atomization (near-nozzle flow), Sibendu Som (Argonne) Evaporative diesel spray, Caroline Genzale (Georgia Tech) Reactions that lead to ignition, Evatt Hawkes (UNSW) Combustion (lift-off length, flame structure), Jose M Garcia-Oliver (CMT) Emissions (soot, NOx, UHC), Scott Skeen (Sandia) Spray B (diesel) in engines, Louis-Marie Malbec (IFPEN) Spray G nozzle geometry and internal nozzle flow, Chris Powell (Argonne) Evaporative Spray G (external, plume interaction, flash boiling), Daniel Vaquerizo (CMT) Spray G (gasoline) in engines, Wei Zeng (Sandia) & Brian Peterson (Edinburgh)

ecn.sandia.govECN 4N/8Sept 2015ECNWhat is the spirit of ECN?A forum for open discussion and synthesis of modeling and experimental results, not usually found at conferences.Synthesis creates expert reviews on topics.We want to know what does NOT work, what is broken.Airing our dirty laundry.so that it can be cleaned!Policy is to not duplicate conference (JSAE) presentations.Not highlighting individual laboratories or groups, but rather, common research problems.

As ECN participants, we have come to know the word guidelines:Guidelines for each topic prepared one year ago to identify the major objectives and target conditions for ECN4Data submitted 3 months agoThough hard to believe, sometimes the deadlines and guidelines slip a littleAs with all things, Disney has the solutionOur inspiration comes from the Pirates of the CaribbeanApparently, the pirates dont always follow their own code exactly, but in the end, things work out.Guidelines of the ECNECN 4N/8Sept 2015ECN

ECNTo have fun together!To share openly in a friendly exchangeA dress code Please dress casually and plan to join together for the final session.

Even though imperfect, your work is making a difference, and it is appreciated!Stay in the ship.well soon find the treasure!The Code of the ECNECN 4N/8Sept 2015ECNECN4 preparation involved a tremendous amount of work, hours of data analysisCollection of the data for presentation on the same graph is a major accomplishment, but identifying reasons for the differences is the key to progress.

Our message to session coordinators and co-organizersLets use ECN4 to look back at the original objectives and perspectivesProvide a review and synthesis including past work before ECN4Draw conclusions comparing the achievements with the initial objectivesIdentify the most significant weaknesses in current modeling and experiment, and provide recommendations about how these weaknesses can be addressed.
