The overall goal of the flame chemistry working group is to obtain fundamental combustion and emission properties of low and high pressure flames, to validate kinetic and transport models, and to develop accurate and computationally efficient models capable of predicting turbulent combustion of future transportation fuels. Experimental data of laminar and turbulent flame speeds, flame structures, extinction/ignition limits, and soot/NOx emissions will be measured for hydrogen, hydrocarbons, alcohols, and important ethers, aldehydes, and ketones up to 30 atm. Kinetic models and transport properties of these fuels will be validated and improved. A method using large eddy simulation(LES), probability density function (PDF), and in situ adaptive tabulation (ISAT) to include the turbulence-chemistry interactions and to enable the efficient implementation of detailed mechanisms in turbulent flame simulations will be developed.
