BOUNDARY DISTURBANCES NEAR AN UNDERWATER EXPLOSION BUBBLE
Abstract
High speed photographs of a number of underwater explosions of 0.2 gram lead azide charges were made. For moderately deep explosions (where the charge depth is one to two maximum bubble radii), water jets above the surface and tubes of air extending down from the surface appeared at points where cables penetrated the surface. Similar phenomena were observed when cables were not present; however, the magnitudes were generally smaller. The occurrence of these phenomena is qualitatively related to Taylor's Instability Theory. If the characteristics of the model explosions of this study are presumed to scale geometrically full-scale nuclear explosions it can be tentatively concluded that: For moderately deep explosions, atmospheric air flows into the tubes and toward the explosion bubble, and the most likely effect is somewhat increased mixing of radioactive products with the water.
