Abstract
The purpose of this study is to obtain an improved method for numerical solution of supersonic flow past a wedge shaped body. Several reports have obtained numerical solutions for supersonic flow past blunt nosed body, and in every case the method adopted can be described as an inverse marching process. This method was applied to a wedge shaped body, thus requiring a elliptical type equation to be solved. In the conventional method, the solution is complicated because that the differential equation includes other terms in addition to velocity terms. In this paper, however, the equation is proposed to facilitate the solution process, as the pressure and density terms are eliminated from the equation so that it is composed solely of velocity terms. An initial application is discussed which constructs the solution starting from shock waves, the Taylar-Maccoll solution. Then, the inverse marching process is subsequently applied in which the solution proceeds from shock waves to surfaces of a rigid body with modification in consideration for boundary conditions. This method makes the solution simple and enhances accuracies in the approximation, with satisfactory results being obtained. 9 refs., 16 figs.
