Welcome

The 2nd International Workshop on Flame Chemistry will be held on Aug.2-3, 2014 at Hyatt Regency San Francisco, San Francisco, USA.

The goal of this workshop is to assemble experts in combustion chemistry, flames, kinetic modeling, and diagnostics to identify the gap of knowledge and pathways for the development of predictive high pressure and low temperature flame chemistry and to establish framework of collaborative research.

Scope

With increasing concerns of energy security and climate change, development of alternative fuels and advanced engine technologies using high pressure, low temperature, thermal and compositional stratified flow, homogeneous charge compression ignition, flameless, pressure gain combustion, and non-equilibrium plasma assisted combustion at near flammability limit conditions provide potential approaches to increasing energy conversion efficiency and reducing air pollutant emissions. For a foreseeable future, combustion with renewable fuels will remain as a major energy conversion methodology for even a more extended period than previously forecast. New combustion technologies at extreme conditions often lead to new flame regimes, increased flame instability, incomplete combustion, and strong chemistry and transport couplings. Biofuels will significantly change the engine and emission performance. As such, it is of great importance to advance fundamental understanding of ignition and flame chemistry at extreme conditions to enable new fuels and to achieve accurate control of ignition, heat release rate, combustion instability, and flame flashback, and emissions.

Theme

The workshop will address the following challenges in flame chemistry,

v What are the new findings and the major knowledge gaps in understanding ignition and flame chemistry at extreme conditions?

v How to formulate theoretical and experimental strategies to narrow the knowledge gap and to develop better predictive kinetic models?

v What are the major differences in chemistry between homogeneous ignition and laminar and turbulent flames?

v How does low temperature chemistry affect ignition and combustion in high pressure HCCI, PPCI, RCCI, and gas turbine engines?

v How can we quantify the fidelity of high pressure flame chemistry and transport data?

v How can we extract constraining information for model construction from macro measure ignition delay time, flame speeds, and extinction limits?

v What diagnostics can we apply to high pressure systems?

v How does turbulence and chemistry interact in high pressure and Reynolds flows?

v Can this workshop formulate collaborative relationship in research and education?

v Can this workshop make some focused recommendations of the grand challenge topics in chemistry to combustion research community?

Policy

The Flame Chemistry Workshop is a satellite meeting that should complement the Combustion Symposium Program of the Combustion Institute and avoid conflicts. Accordingly, our policy is that materials presented at the workshop should not duplicate information in formal Symposium papers and oral presentations, although some results may be used in common.

Sessions

The Workshop Program includes four invited lecture sessions, one poster session, and two panel discussion sessions.
