Dynamical Model for Explosion Injury to Fish.
Abstract
A new method is given for calculating kill probability for bladder fish subjected to the rapidly varying pressure field of an underwater explosion. The method consists of an approximate calculation for the extreme values of compression and extension of the fishes' gas-filled swim bladder in response to the explosion pressure wave. The calculations are made for the damped radial oscillations of a spherical air bubble in water. The kill probability is then calculated as an experimentally deterimined function of the ratio of maximum to minimum radius during the oscillatory response. For each species of fish the effective bubble radius for the calculations is determined thru correlating the observed injuries with the calculated radius ratio. (Author)
