NUMERICAL SIMULATION OF 3-D HYPEKSONIC FLOW AND NEAR WAKE AROUND BE-ENTBY VEHICLE

The knowledge of complex three-dimehsional hypersonic visous flow over re-entry bodies is of great importance in the preliminary design of atmospheric re-entry vehicles.The thin-layer Navier-Stokes equations are solved with Harte-Yee's second-order TVD fiuitedifference scheme for three-dimensional hypersonic flowfields over a re-entry vehicle, whereM_∞ =7.35,Re_∞=7.5×10￣5,α=10°,20°。The detailed flowfield structures are given.The pressure distributions along body surface at various angles of attack are compa...
