DEVELOPMENT OF PROBES FOR MEASURING THE MAXIMUM RADIUS OF UNDERWATER EXPLOSION BUBBLES,

Abstract

An instrument for finding the position of a gas-water interface was developed and successfully used to measure the radius of an underwater explosion bubble. The change in conductivity between two parallel rods as the interface moves along the rods is recorded on film by an oscilloscope. Simultaneous photographic and probe measurements of maximum radii showed agreement within slightly over one percent. Bubble parameters obtained with the probes show some disagreement with free water measurements, possibly the result of flattening of the assumed spherical bubble by bottom and surface proximity.
