OSTI ID:6854692
The Euler equations for a perfect gas are formulated in terms of a surface coordinate system with the four dependent variables u, v, p, and T. The governing equations are written in a form where the equations for conical flow, steady two-dimensional flow, or unsteady two-dimensional flow are readily obtained. The steady equations for supersonic flow are solved with a mid-point implicit scheme. Conical flow solutions are calculated or a marching procedure is used to obtain the shock layer flow along smooth pointed bodies. Numerical results for inviscid flow on an ogive are compared with experimental results and with simplified governing equations which use thin shock layer and parabolic equation approximations.
