Note (General): This paper treats the Parabolized Navier-Stokes equations. We previously solved the Euler equations by finite volume method. The results showed good agreement with experimental results. Then, this was extended to include viscous effect by solving the Navier-Stokes equations, using Beam-Warming scheme. These results also showed good agreement with the Euler code. we also could obtain thermal effect on the Shuttle-like body. In this paper, we employed the PNS equations in order to reduce CPU time. Actually, the calculation time was reduced to some thousands as much as the thin layer Navier-Stokes equations. The two cases were calculated. One is hemisphere cylinder, and another is hemisphere-eliptic cylinder at an attack angle. The first case was compared with the time-dependent thin-layer NS equations. The comparison between them was good. The second case showed clear effect of attack angle such as the turn of flow from the lower surface to the upper surface.
