Evaluation of Concepts for Measuring Dimensions of Bubbles Produced by Underwater Explosions

摘要

This report discusses the feasibility of several methods which have been proposed for obtaining measurements of the radius of bubbles resulting from underwater explosions of yields ranging from 1 to 20 tons of TNT. The methods considered are: (1) Photographic, (2) Acoustic, (3) Probe conductivity, (4) Electrical conductivity, (5) Field kinematics. For the yields considered, the photographic and acoustical methods are shown to be of little or no use, whereas the remaining three methods look promising in varying degrees. (Author)
