摘要：

Numerical investigation of hypersonic flow and heating over two models of an interplanetary probe was carried out at Mach numbers from 6 to 20 and Reynolds numbers Re,, D from 0.7x10(5) to 16x10(5). The models differ mainly by the shape of the back surface simulating the payload container. The Reynolds number, at which laminar-turbulent transition takes place in the near wake, was defined at Mach numbers M =6-8. It was shown that at turbulent base flow, the heat flux to the back surface of a blunted body can be comparable with the heat flux at the forward stagnation point. The results of numerical flow within the framework of Navier-Stokes and Reynolds equations simulation were compared with the experimental data.
