A Navier-Stokes Solution and a Radiation Analysis for a Strong Shock Wave Propagating in Air Between Adiabatic Plates

Abstract

An analytical investigation for radiation phenomena in the shock induced boundary layer along a flat plate is presented.The Navier-Stokes equations coupled with thermochemical nonequilibrium are numerically solved for a strong shock wave propagating in air between parallel plates. The two temperature model is used as thermal nonequilibrium model and the plates are assumed as adiabatic and noncatalytic. The shock Mach number is 30.0 in the initial pressure 13.3 Pa. A velocity slip condition is applied on the plate surface. The radiation is evaluated by a numerical code based on the NEQAIR. The result shows the existence of intence nonequilibrium radiation in the shock induced boundary layer.
