Where: The Arts Building, Trinity College, Dublin

Delegates are invited both to participate in the ongoing research programs of the ISF Workshop and to attend the fourth meeting of the series in Dublin.
The ISF is an ongoing, open forum for international collaboration between experimentalists and modellers in which target flames are investigated collaboratively throughout the year.
Each workshop compares the latest results of numerical predictions with each other and with the measured data from the target flames, each of which is purpose-designed for model development and validation while also being relevant to practical application.
All data are archived through the ISF’s open-access web-site.
Each meeting reviews the latest progress, revises research priorities and selects targets for the following meeting. The workshop addresses all aspects of the formation, oxidation and emission of soot, together with its role in radiation and pollutant emissions from simplified flames of key classes of technology.
-
Aims of the ISF Workshop
- 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;
-
Objectives and targets for ISF-4
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
-
Workshop programs
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;
-
Joint session with other international forums
