Abstract:

A theory of the propagation of shock waves from explosive sources was presented in NDRC Report A-318 OSRD - 4814. In that report, a pair of ordinary differential equations for peak pressure and shock-wave energy as functions of the distance from the source were formulated from the equations of hydrodynamics by imposing a similarity restraint on the shape of the energy-time curve of the shock wave. Two-parameter families of peak pressure-distance curves are obtained by the solution of these propagation equations. The parameters are conveniently chosen as the initial values of the pressure and shock-wave energy. In the present report, tables and graphs of the two-parameter families of curves for shock waves from explosive sources in sea water are presented. A method is outlined for the determination of the parameters from experimental values of the peak pressure and impulse over a limited range of distances from the source.
