Abstract 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.
Highlights Numerical simulations of 3D flow of a gas mixture over a flat surface are presented. An effective numerical model based on the analytical solution is created. Two ways of determining the heat removal are considered. The 3D numerical simulations in combustion chamber of hybrid rocket are performed.
