摘要

The interactions of the shock with the boundary layer of the cold gas behind the contact in many different conditions, i.e. three kinds of test gases and three kinds of sound speed ratios across the contact, were explored by numerical study. The trajectories of the transmitted shock in cold gas flow and the development of shock bifurcation in the process of interaction with boundary layer are illustrated by many kinds of figures (e.g. the time-distance diagrams of the acoustic impedance contours on the axis, the pressure and density contours and the static pressure distributions on the axis).
