A contact discontinuity tracking method with a specially designed moving grid is developed to eliminate the interface smearing completely. In order to precisely locate the contact surface, an updated Riemann solver for unsteady one-dimensional inviscid flows is also developed to allow consideration of the specific heat ratio change across the shock wave. These two new computational techniques are illustrated in a high Mach number shock tube flow field computation.
