Parametric studies using the plane Couette flow as a simple model for shear flows to test different physico-chemical aspects of the very complex high-temperature chemically reacting flows occurring in hypersonic flow configurations are under way. Some typical results on the dissociation/recombination reactions of diatomic gases as to the effects of the choice of transport coefficient modelling and reaction rate coefficient data on the practically relevant quantitites such as heat transfer and skin friction at the solid walls are discussed.

An implicit fully coupled numerical method for modeling of chemically reacting flows is presented. Favre averaged Navier-Stokes equations of multi-component gas mixture with nonequilibrium chemical reactions using Arrhenius chemistry are applied. A special method of splitting convective fluxes is introduced. This method allows for using spatially second-order approximation in the main flow region and of first-order approximation in regions with discontinuities. To consider the effects of high-speed compressibility on turbulence the author suggests a correction for the model, which is linearly dependent on Mach turbulent number. For the validation of the code the described numerical procedures are applied to a series of flow and heat and mass transfer problems. These include supersonic combustion of hydrogen in a vitiated air, chemically reacting flow through fluid rocket nozzle, afterburning of fluid and solid rocket plumes, fluid dynamics and convective heat transfer in convergent-divergent nozzle. Comparison of the simulation with available experimental data showed a good agreement for the above problems.
