Effects of Dissociation Relaxation upon Reflected Shock Waves and Unsteady Thermal Boundary Layers

Abstract

A numerical analysis was made for a dissociative reflected shock wave and its invicid flow field, and for unsteady thermal and concentration boundary layers developing at the end wall of a shock tube. It was shown that an entropy layer is formed adjacent to the end wall. The thermal boundary layer was found to have an overshoot of temperature which was sometimes higher than that outside the boundary layer. The concentration boundary layer was found to develop mainly due to the convection of highly dissociated gases from outside the boundary layer. It was found that self-similar boundary layers become valid finally.
