Difference scheme for 2D nonstationary equations of gas dynamics in three temperature approach

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