Modified numerical scheme for H3T program complex

Numerical scheme for numerical modelling 2D non stationary flow of the heat — conducting gas in three temperature approach on the curved grids is studied. Differential equations of the problem are splinted for the processes: gas dynamic process and heat — conductivity process. For linearizing nonlinear system obtained in the heat conductivity, it is used Nyuton approach. Algebraic equations are solved by GMRES approach using SPARSKIT software. Numerical scheme is verified by numerical tests.
