Numerical Simulation of the Explosives Effects of Two Closely Spaced Pyrotechnic Pods

Abstract

This report describes some computer simulations to study the effects of two pyrotechnic noise-generating pods which deflagrate in close proximity, at, or nearly at, the same time. Some modifications to the computer code HULL, to improve the efficiency of the calculations, are described. The calculations show that though there is reinforcement of the shock wave between adjacent pods, the increased effect on nearby personnel is small. The effect of non-synchronous deflagrations is less than synchronous ones. The overall single pods as far as hazard is concerned, though with more pods in a confined space there is an increased chance of a person being located in a hazard region.
