摘要：

Analytical study of aerotherrnodynamics is an important problem to the flight control and the vehicle thermal protection system (TPS) design. The flow fields of the Stardust return capsule aviating in the earth atmosphere of four cases (the Mach number varying from 12.2 to 30.7) were simulated by using the conservation integral form of Navier-Stokes equations with multi-species, nonequilibrium molecular thermal excitation and chemical reactions, based on the high-resolution total variation diminishing (TVD) scheme. Aerodynamics and heat transfer of high-temperature and high-velocity flow field behind bow shock were studied, and the aerodynamics coefficient and the wall heat flux are in good agreement with fight data. These results are useful for designing correlative vehicles' TPS.
