The relaxation effects influence on the formation of a heat flux in a wall when a viscous shock wave is reflected from it

Abstract

Results of calculation of heat flow in solid wall from iron or bismuth are given. Relaxation effects are taken into account on the example of viscous shock wave at Mach number of shock wave M = 5. The results of calculating the heat flow in the wall of bismuth and iron when reflecting a viscous shock wave profile from it in the presence of relaxation properties showed that the heat front is formed the later the higher the relaxation coefficient. The noticeable lag of the thermal front in bismuth with respect to iron is associated with a significantly lower value of the thermal conductivity coefficient.
