A Numerical Analysis on the Ionized Boundary Layer along a Shock Tube Side Wall

Abstract

A numerical analysis was made for the ionized reacting, thermal non-equilibrium boundary layer which develops along a shock-tube side-wall, behind an ionizing incident shock wave. The boundary layer was found to change according to the ionization relaxation of the inviscid flow behind the shock wave. It was shown that the temperature in the boundary layer becomes higher than the temperature outside of the boundary layer in the rapidly ionizing region behind the shock wave. The numerical solutions were obtained for the case of the incident shock Mach number Ms＝13, initial pressure p₁＝10 torr and initial temperature T₁＝300°K.
