A Two-Dimensional Unsteady Method of Characteristics Analysis of Fluid Flow Problems - MCDU 43

Abstract

A computer code for solving two-dimensional, unsteady, inviscid, fluid-flow problems has been developed. Presented are details of the method-of- characteristics formulation, the treatment of the boundary conditions, and the numerical solution technique. In a sample problem of a cylindrical blast wave, the error to the exact solution is less than 0.05% at all points after 50 times planes of calculation.
