The most important step in the correct solution of discrete analogs of the equations of gas dynamics for the high-speed flow of a compressible chemically active gas using grid methods is to ensure sufficient grid resolution of regions with high gradients of gas-dynamic parameters, that is, the region of the departed curvilinear shock wave compressed and boundary layer. In this work, the grid independence of the main flow parameters on the dimensionality of the computational grid was checked on the problem of flowing a sphere by a high-speed flow of a gas mixture. The dependences of gas-dynamic flow parameters on the grid resolution along the normal to the sphere surface are revealed. The conclusions about the sufficiency of the grid resolution for a particular problem have been made.
