Abstract
In this paper, we propose a numerical method for solving the problem of the propagation and gorenje of a methane jet in an axisymmetric satellite air flow. Dimensionless equations of the turbulent boundary layer of reacting gases in the Mises coordinates are used for modeling. To solve the problem in the Mises coordinates, a two-layer, six-point implicit finite-difference scheme is used, which provides a second-order accuracy of approximation by coordinates. Due to the nonlinearity of the equations of conservation and transfer of substances, an iterative process was organized. Separate results of the computational experiment are presented. Comparison of the calculation results for the change of the axial flow temperature according to k−ε and Prandtl models of turbulence and experimental data.
