Chemical Modeling for Large Eddy Simulation of Turbulent Combustion

Abstract

This research program consists of two major efforts: (I) the development of improved turbulence/chemistry interaction models for large eddy simulations (LES), and (II) the development of reduced kinetic mechanisms for JP-8 surrogate fuels based on a component library approach. With regard to part I, a new numerical method for solving the level set equation to understand the effect of numerical errors was developed. This method has interesting implications for turbulent burning velocity models and can be used potentially for error estimation in LES. With regard to part II, an efficient multi-stage approach for the reduction of large kinetic mechanisms was developed and validated.
