In this paper, the interaction phenomena of the reflected shock wave with the contact surface in a shock tube were investigated by numerical simulation in order to clarify the formation mechanism of the pseudo-shock wave. The computations were carried out by solving the two-dimensional, time-dependent and compressible Navier-Stokes equations by means of TVD method. The formation process of the pseudo-shock was visualized by the plots of the contour lines of the pressure andthe density, the velocity vectors, and the stream lines in the flow field, and the pressure distribution on the wall.
