Abstract : Th vortex element method and the transport element method are developed for the numerical simulation of the Navier Stokes equations and the energy and species conservation equations, accurate simulation of the governing equations at high Reynolds and Peclet numbers, without resorting to turbulence modelling. Finite rate chemical reactions, finite compressibility and finite heat release rates are also considered in the formulations of the numerical schemes. To validate these methods, we are obtaining solutions for reacting shear layers, both homogenous and heterogeneous, under various idealizations, and comparing the numerical results with experimental data. The solutions are also analyzed to investigate the mechanisms of turbulence combustion interactions. Keywords: Turbulent combustion.
