Estimating Water-Shock-Induced Airblast from Detonations in a Medium Overlain with Water

Abstract

A geometrical shock wave transmission model is used to determine water surface peak spall velocities above single-charge cratering detonations in a medium overlain by a thin-to-moderately-thick layer of water. These velocities, in conjunction with an acoustic simple source treatment, predict the water-shock-induced airblast from such events. Required input data include the acoustic impedance and shock wave transmission properties of the cratering medium in the inelastic and elastic regions. The method is intended to predict far-field airblast in the 'low' overpressure regime, for which case the acoustic simple source treatment is valid. A computer code called 'MULTIMEDIA' is included with this report as an aid to numerical prediction calculations.
