The article examines the features of numerical simulation methods for convective heat transfer on high-temperature ideal viscous gas flows near the surfaces with different configuration. The study focuses on the problems of supersonic plane-parallel flow near the impermeable plate as well as the problems of subsonic flow of the compressible gas in a channel with a circular cross-section and of transonic flow in axisymmetric channels. For the problems under study, we analyzed RANS methods of gas flow description. Moreover, we gave recommendations on the choice of the mesh elementary volumes parameters for the different turbulence models. Findings of the research show that provided the recommendations given are followed, it is likely to determine the convective heat flux values with an acceptable accuracy (compared to other experimental data). The results of the research can be applied in the thermal state modeling for assembly parts of high speed aircraft, their propulsion systems as well as for assembly parts of power and high enthalpy industrial process systems.
