Vortex Simulation of turbulent Combustion

Abstract

During the second year of this effort, we focused on introducing the effect of combustion in the computation of the spatially, developing shear layer. and continued our analysis of the effect of density variation and upstream forcing on the growth of the mixing zone of the shear layer, We have developed a flame sheet model for the simulation of combustion at high Damkohler numbers where the application of the transport element method proves to be rather expensive, The model uses the instantaneous local strain rate as an input from the flow computations and, by integrating a one dimensional equation, computes the rate of burning within each flamelet within the domain.
