Michael Mueller Awarded Combustion Institute’s Tsuji Award

Professor Michael Mueller from Princeton University, program leader for the ISF Turbulent Flames program, was awarded the 2022 Hiroshi Tsuji Early Career Researcher award from the Combustion Institute, which was presented at the 39^th International Symposium on Combustion. This award recognizes excellence in fundamental or applied combustion science within four to ten yours of completion of a doctoral degree. Amongst other contributions, Professor Mueller has made significant contributions to the computational modeling of soot in turbulent reacting flows. Additional details are available from the Combustion Institute.

The ISF Committee is pleased to have introduced to our sixth meeting a series of prizes for PhD students and early career researchers, both for the best 3 minute presentation and for the best poster.  In so doing, we also wish to thank Dr Benedetta Franzelli (Laboratoire EM2C) and Dr Zhiwei Sun (The University of Adelaide), for organising both the posters and the awards.

• To advance understanding and predictive capability of flames with combustion-generated particles, including soot, to identify gaps in the understanding and to coordinate research programs to address them;
• To advance understanding and predictive capability of high temperature reacting flows (HTRF) used to produce valuable carbon-based nano-particles and other products, together with fuels, such as hydrogen, with processes such as flame synthesis and pyrolysis;
• To identify well defined target flames/HTRF and coordinate additional experiments that provide suitable data for model development and validation, spanning a variety of reactants and flow-field environments in each of the research programs;
• To establish an archive of the detailed data sets of target flames/HTRF with defined accuracy and to provide a forum for the exchange and dissemination of these data;
• To advance understanding by establishing clear and consistent definitions and terminology.

1) To advance understanding of the strengths and limitations of various modelling approaches for sooting flames and HTRF by detailed comparison of predictions with experimental/DNS data of the following environments:

   a) Turbulent high temperature reacting flows

• DLR pressurised swirl flame
• Sandia JP8 jet flame
• Adelaide bluff body flames

   b) Laminar high temperature reacting flows

• Laminar opposed jet flames under conditions and fuels matching turbulent target flames
• Premixed flames under conditions matching turbulent target flames
• Laminar flames with a series of fuels
• Adelaide forced laminar flames

2) To assess the most effective options with which to advance previous work of the ISF community and to address other HTRF environments involving carbon-based nano-particles;

3) To review progress in experimental and numerical methods and coordinate programs to continue their advancement.

The first aim will be met through comparison of recent data contributed by the community that
compares experiments and models from across the community within the following two research
programs, for which contributions are invited via the relevant Program Leaders:
• Laminar reacting flows: Chemical Kinetics (PAH, inception, growth and oxidation); particle
dynamics (moment methods, sectional models, coalescence vs. aggregation); effect of pressure
• Turbulent reacting flows: jet flames, bluff body flames, swirl flames, pool fires, influence of
scale, and effect of pressure.

The second aim will be met through special discussion panels involving invited presentations from
leaders in the field, as listed in the program.

The third aim will be met through open discussion addressing progress and challenges, facilitated by
the committees, seeking to refine current understanding of the state of the art in developing
predictive capability in these challenging environments.

Informal discussions are facilitated through the poster session, details of which will follow soon.
