摘要：

Numerical simulations of three-dimensional flow of a gas mixture with chemical reactions over a flat thermally destructing material surface are presented. To create an effective numerical model, two ways of determining the heat removal are considered, and a comparison with the analytical solution obtained within the frame of the boundary layer approximation is represented. As an example, the numerical simulations of three-dimensional flow in combustion chamber of hybrid rocket are performed. The temperature maps and molar fraction of fuel within the chamber for different times are shown.
