A TIME-DEPENDENT NUMERICAL METHOD FOR CALCULATING THE FLOW ABOUT BLUNT BODIES.

Abstract

A finite difference method can be used to threat inviscid flow about blunt bodies traveling at supersonic speeds. The method employs a finite difference scheme, stabilized by artificial dissipative terms. Considerable flexibility in the magnitudes of these artificial dissipative terms is permitted. A coordinate transformation reduces the computer storage and the computation time by improving the finite difference mesh point distribution. A computer code that treats axisymmetric flow over spherically blunted cones compares favorably with other numerical solutions. (Author)
