Transmission of a Shock Wave Across an Evacuated Barrier

Abstract

The transmission of a one-dimensional shock wave across an evacuated barrier in a liquid is modeled. In this model the interaction of the shock wave with the incident side of the barrier causes the liquid to cavitate. The cavitated liquid then moves across the barrier and collides with the liquid on the opposite side of the barrier, thus setting in motion a transmitted wave. The pressure history of the transmitted wave is determined from that of the incident shock wave. The pressure history of the transmitted wave is determined from that of the incident shock wave. Although the impulse of the transmitted wave is the same as that of the incident shock wave, the transmitted wave can have considerably lower peak pressure and energy flux density. Possible extensions of this model are discussed. Also, potential military and industrial applications are considered.
