抄録

The interaction of a reflected shock wave with the boundary layer in a shock tube has been numerically analyzed. In calculation, the same conditions as the experiment by Matsuo et al. regarding a rectangular shock tube have been employed. The numerical scheme employed here is the explicit-implicit hybrid scheme, which was developed at our laboratory, along with Godunov's exact Riemann solver. The solution adaptive mesh refinement method and geometrical mesh refinement method were also used to increase the accuracy and efficiency of the calculation. The results clearly show a complicated flow field with a recirculation region enclosed by bifurcated shocks. Moreover, it was made clear that the total enthalpy of the stagnated gas is dissipated by the viscous interaction between the quasi-shock structure and the boundary layer.
