Simulations are performed for reflection of shock waves at an end wall in noncondensable and condensable gases in a shock tube by numerically solving the Navier-Stokes equations subject to the appropriate boundary conditions using the explicit TVD scheme. Numerical solutions obtained here are compared with those of the Boltzmann equation of BGK type. Good qualitative agreements are obtained between the two solutions for both noncondensable and condensable cases. Hence, the Navier-Stokes equations with the appropriate boundary conditions are shown to be adequate for simulations of gasdynamics phenomena on a scale of the mean free path. Some appreciable discrepancies, however, appear between the numerical solutions of the Navier-Stokes equations and those of the Boltzmann equation as the incident-shock Mach number increase.
