Abstract
Via using continuum model and dimensionless transformation method, the effect of heat conduction is studied in shock wave structure of non-ideal gas. It turns out that due to the presence of heat conduction, gas velocity in upstream of shock front decreases and it in downstream increases, respectively, the gas temperature or entropy change significantly increases, the maximum of gas viscous stress decreases, and the limiting Mach number of the continuum model and the shock thickness increase. Then, with the increase in the gas non-ideality, the difference in gas viscous stress caused by heat conduction decreases, and the growth rate of gas entropy change increases. The effect of heat conduction in shock compression mechanism is revealed.
