The 6^th FCWS was held virtually on Zoom. Sessions covered PAH and soot formation chemistry, low-temperature chemistry, gas-phase kinetics beyond combustion (plasma, catalysis), large mechanism development (thermochemistry, uncertainties, machine learning), low-carbon and sustainable aviation fuels, and thermal runaways. The workshop was organized by Nils Hansen (Sandia National Laboratories).

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, HCCI, cool flames, flameless combustion, ammonia combustion, pressure gain combustion, supercritical combustion, and plasma assisted combustion at near flammability limit and non-equilibrium 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. New combustion technologies at extreme conditions often lead to new flame regimes, increased flame instability, incomplete combustion, and strong chemistry–transport couplings. Biofuels will significantly change engine and emission performance. It is therefore 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, flame flashback, and emissions.
