Abstract

A computer simulation is used to study the behavior of a fluid which has been set into motion by a point explosion below a bounding free surface. Of particular interest is the interaction between the incident shock wave and the reflected rarefaction signal which, under certain conditions, can overtake the shock front. Onset criteria for the envelope which separates the region of irregular from that of regular rarefaction, the nonspherical shape of the shock front, and the pulse profile for several depths of burst covering both strong and weak shock interactions with the surface will be discussed.
