Abstract Keywords
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 super-
sonic 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
