Abstract

The numerical method for high-speed turbulent gas flows with non-equilibrium chemical reactions has been developed. The full Navier-Stokes system (with Reynolds-Favre averaging) is being used. The system is solved using the fully-coupled implicit numerical approach. The modified Steger- Warming split method is used for connective flux, treatment. Sources in the reaction equations are presented in the implicit form.
