Numerical simulation of turbulent flames using vortex methods. Annual report No. 3, 1 September 1986-31 August 1987
Th vortex-element and transport-element methods are developed for 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 modeling. 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, solutions are being obtained 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.
