| Abstract: | The three dimensional hypersonic viscous flow of perfect gas over a capsule is calculated numerically. The Navier-Stokes equations are taken as the governing equations. The implicit NND scheme is used for the shock capture. The computation region is involved with the full flowfíeld from the nose to the base. The flowfield properties and the areodynamic force coefficients thus obtained are good compared with the experiment results. |
