PHOTOGRAPHY OF UNDERWATER EXPLOSIONS. 2. HIGH SPEED PHOTOGRAPHS OF BUBBLE PHENOMENA
Abstract
The techniques developed recently at the Underwater Explosives Research Laboratory for photographing underwater explosions in the open ocean are described. High speed motion pictures of explosion product bubbles from 1 oz and 1/2 lb charges of various explosives are shown. These pictures were taken at depths ranging from 200-700 ft. The oscillation of the bubble can be followed through several periods, and various details observed such as the rate of bubble growth, maximum bubble radius, surface irregularities on the bubble and the effect of charge shape and casing. High speed motion pictures are also shown of charges close to the surface of the water. Migration of the bubble, its interaction with the water surface and the appearance of cavitation bubbles are demonstrated.
