THE IMPACT OF REACTION MECHANISM COMPLEXITY IN LES MODELING OF LIQUID KEROSENE SPRAY COMBUSTION

A. ┼kerblom, Lund University, Sweden

Due to the high computational cost of LES and detailed chemistry models for aviation fuel, reaction mechanisms employed for finite-rate combustion in LES must be compact yet realistic. The influence of reaction mechanism complexity on LES results should therefore be measured, so that appropriate mechanisms can be chosen for future studies and new LES-optimized mechanisms can be developed.
