Modeling of pressure waves formed during detonation and combustion of gas mixtures
Abstract
A comparative analysis is presented of the data in the literature on explosions of explosives and gas mixtures based on socalled energy similarity curves, where the pressure and impulse field for the explosive is represented as a function of the reduced radius referred to the cube root of the energy, or to the radius of the charge. It is found possible to formulate energy similarity laws for spherical detonation explosions of clouds of gaseous mixtures in terms of pressure and impulse, and that existing data are described by a unified relationship, within the limits of acceptable experimental error. Inasmuch as the experimental errors are fairly large, however, it is inadvisable to use the socalled trotyl equivalent as a rigorous quantitative characteristic.
