The shock wave structure in a heat-conducting gas in view of heat flow relaxation

The shock wave structure in ideal heat-conducting gas is investigated with the thermal conductivity law, taking into account the relaxation of heat flow, for constant values of thermophysical parameters. It is shown that the wave structure may consist of a jump and gas heating zone ahead of the shock wave or a relaxation zone behind the wave front. For certain values of the parameters, the wave structure may consist of two discontinuities of thermodynamic functions and a zone of continuous variation between them. The front width of such a shock wave is determined.
