Abstract:

The report presents a review of the experimental data on the refraction of underwater explosion shock waves. For experiments in the ocean and in flooded quarries, pressure-vs-time recordings of the refracted pulses are described, and their characteristics are related to the appropriate regions of the calculated ray diagrams shadow zones, caustics, single-arrival, and multiple-arrival regions. Although the experiments were directed primarily toward explosive applications, the results are useful for acoustic applications also in that pulse recordings provide clear data on pressure amplification, arrival angle, relative arrival time, and phase shift, for each arrival in a multiple-arrival pulse.
