Three dimensional model of aerothermodynamics of entering space vehicles

Three-dimensional computational fluid dynamics (CFD) model of aerothermodynamics of descent space vehicles is described. The model is realized with regular multi-blocks curvilinear calculation grids in computer code NERAT-3D.
Numerical simulation results for convective and radiative heating of model of space vehicle studied in European scientific program EXOMARS of Mars exploration are presented. Examples of 3D calculations of flow fields around model of space vehicle at angle of attack are presented and analyzed, as well as the influence on these results of grid topologies
