Abstract
The problem of numerical modeling of the effect of radiation processes on gas dynamic parameters around a descent space vehicle in the Earth’s atmosphere is studied. A relatively new approach is suggested of direct modeling of radiation processes oriented to the use of high performance multiprocessor computer systems. The physical model of radiation transfer is described by a diffusion approach with a discretization of radiation and absorption spectra and a set of quasigasdynamic equations. The computations were carried out on both triangular and hybrid locally refined grids. The gas-flow modeling results taking into account radiation processes are represented for bodies of different shapes.
