Finite Amplitude Propagation of an Underwater Explosion Shock Wave along a Strongly Refracted Ray Tube

Abstract

The effect of wave overtaking on the peak pressure of refracted underwater explosion shock waves is estimated by means of a finite amplitude calculation for the wave propagation along refracted ray tubes given by simple ray theory. The results indicate that a reduction in peak pressure occurs due to increased wave-overtaking along refracted ray paths to first caustics. Reductions in the peak pressure no greater than 5% occurred for the particular refractive conditions treated, but preliminary work with other conditions indicates much greater reductions can occur.
