THE EFFECT OF AN AIR-BUBBLE SCREEN ON PRESSURES DUE TO UNDERWATER EXPLOSIONS,
Abstract
A screen of air bubbles interposed between a small-scale underwater explosion and a pressure gage is found to cut off the pressure peak, to reduce slightly the transmitted impulse, and to reduce greatly the energy reaching the gage. Accurate observation of the later stages of the action requires the use of gage cables that do not introduce spurious signals. Attention is called to some of the nonlinear properties of bubble screens. A microflash photograph is presented, showing the progress of a shock wave along a thin sheet of air bubbles. (Author)
