A numerical solution of the axisymmetric jet counterflow problem

A numerical computation of a normal shock case in which the shock waves and shear layers are modeled as normal and tangential discontinuities bounding the regions of an inviscid flow is discussed. Within these regions the unsteady gasdynamic equations are solved in finite-volume form on a moving computational mesh. The positions of discontinuities are determined from the jump conditions. The results obtained for values of the ratio of jet total pressure to free-stream total pressure ranging from 10.0 to 100.0 are found to be in agreement with the experimental results obtained by Fleeman and Nelson (1974).
