Abstract:

In an effort to determine the amount of energy transmitted into the water when an explosion occurs above a water surface, both experimental and theoretical investigations were conducted. The experimental study involved detonation of 21-lb spheres of TNT above a water surface and measuring induced water shock at spatial positions underwater. To fully incoroporate the nonlinear characteristics of the airblast into the study, free-air pressure-time data were used as the water surface loading mechanism and the investigation was divided into two phases--in Phase I the generating source was at such a height that the induced water shock could be adequately described by acoustic theory, while Phase II the generating source was nearer the surface and the resulting disturbance field was of a finite amplitude that had to be considered to accurately determine underwater pressure.
