³ÉÈË´óƬ

• To advance understanding and predictive capability of flames with soot, to identify gaps in this understanding and to coordinate research programs to address them;
• To identify well defined target flames and coordinate additional experiments that provide suitable data for model development and validation, spanning a variety of flame types and fuels in each of the research programs;
• To establish an archive of the detailed data sets of target flames with defined accuracy and to provide a forum for the exchange and dissemination of these data;

Objective 1

To advance understanding and prediction of inception-dominated ethylene flames:

• Target 1: obtain new systematic data in inception-dominated laminar ethylene flames (such as counter-flow flames) to achieve conditions for key controlling parameters (such as residence time) that better match those that apply in the existing data sets for turbulent ethylene jet target flames. Data is sought for both atmospheric and elevated pressure conditions.

Objective 2

To advance prediction of sooting flames in the growth/agglomeration regimes of ethylene flames:

• Target 2: obtain new systematic data in growth/agglomerated-dominated regimes of turbulent ethylene flames (such as the recirculation region of bluff-body flames) to achieve conditions for key controlling parameters such as residence time that better match those that apply in the existing data sets for laminar ethylene jet flames. Data is sought for both atmospheric and elevated pressure conditions.

Objective 3

To advance prediction of sooting flames with more practical fuels:

• Target 3: establish a coordinated data base, building on existing data, in the laminar and turbulent regimes, and at a range of pressures, for methane flames and pre-vaporised heptane flames;

Objective 4

To engage with the international community through a joint session with members of the flame chemistry workshop to develop better understanding and models of soot evolution, addressing both:

• PAH chemistry, soot inception, and
• soot oxidation

The workshop is organised around the following two Research Programs, each spanning a range of temperatures and pressures:

• Laminar flames: Chemical Kinetics (PAH, inception, growth and oxidation); particle dynamics (moment methods, sectional models, coalescence vs. aggregation), shock tubes;
• Turbulent flames: Jet flames, bluff body flames, swirl flames, pool fires; influence of scale;

• Flame Chemistry Workshop: Invited panelists addressing soot inception: Prof Tiziano Faravelli, Prof Stephen Klippenstein, Prof Nils Hansen
• TNF Workshop: Invited panelists addressing common challenges: Prof Simone Hochgreb, Prof Venkat Raman, Prof Bill Roberts

• Industry: Roscoe Taylor, Orion Engineered Carbons
