The Preconditioning of Chemical Sources Terms in Equations with Diffusion, Convection and Chemical Kinetics

详细

The reasons of singularity have been considered for finite-differences equations of multi-components hydrodynamics of chemically active gas. To prevent the equations singularity, the preconditioning method is developed. The method is adjusted for modeling of one-dimension gas mixture combustion in the case of extremely fast chemical reactions present.
