【 摘 要 】

The purpose of this article is to investigate the separated flow around the bent-nose biconic, in which the second-order TVD (total variation diminishing) method is applied and the numerical flux is a Harten-Yee type. The governing equation is a thin layer Navier-Stokes equation. The boundary condition on the wall is the adiabatic wall. The whole flow field is laminar. The numerical conditions are as follows: Mach number 7.0, Reynolds number 8.38 . 10(5). The surface pressure distribution at the leeward side is a little higher in the vicinity of the symmetrical plane. This seems to be caused by the development of the vortex at the leeward side due to the separated flow. The location of a separation line and the size are in very good agreement with the experiment. Also the secondary separation is captured very clearly. The characteristics of the separated flow around the bent-nose biconic are clarified.
