THE INVISCID CHEMICAL NONEQULIBRIUM FLOW BEHIND A MOVING NORMAL SHOCK WAVE

Abstract

A time-dependent numerical scheme is used to solve for the chemical nonequilibrium profile a normal shock wave in air. The steady state equations are also integrated using a fourth order Runge-Kutta technique and a comparison is made with the time-dependent calculation. The results agree within one percent except in the region close to the shock. In this region the profiles differ because the time-dependent technique allows calculation through the shock (which is several mesh points in width) and as a result some dissociation occurs.
