Internal and external acoustics and large structures dynamics of cavitating self-resonating water jets

This report describes theoretical and experimental work done by Tracor-Hydronautics on structured, resonating jets to be used in rock-drilling bits. This is a continuation of earlier work, done under contract to Sandia, in the development of cavitating and resonating jets. The phase of the project includes the construction of a large scale flow visualization facility, experiments in the facility, analysis of the experimental data, and some extensions of the acoustic and hydrodynamic theories. All of this effort was directed at the flow regime encompassing high velocity, large pressure fluctuations, non-vanishing Mach numbers, and low cavitation numbers. 24 refs., 94 figs.
