Abstract:
The reasons of degeneration have been considered for finite-differences equations of multi-components hydrodynamics of chemically active gas. To prevent the equations degeneration, 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.
Keywords:
chemical kinetics, equations degradation, preconditioning, quasi-linear elimination.
