A Calculation of the Blast Wave from the Constant Velocity Detonation of an Explosive Sheet

Abstract

Predictions of the blast wave from the constant velocity detonation of a thin explosive sheet have not previously considered the contribution of the postdetonation combustion of the detonation products. This problem is simplified by first considering the explosive material as releasing only energy into an ideal gas medium. This is solved for several energy densities and velocities of detonation. An expression that can predict the shape and location of the shock front from a line source of energy in a hypersonic flow is then developed. The problem is more realistically modelled by considering the explosive sheet to release six distinct mass species, as well as energy, into a mixture of nitrogen and oxygen.
