Abstract

This study investigates blast wave pressures generated from explosions of premixed gases. The blast wave pressures were estimated using a blast model that utilizes the volume variations of a burnt gas as a pressure source. The volume variations were obtained by flame propagation velocities that were measured experimentally. Since the results of this model were in agreement with previous experimental and numerical calculation results, this model can be used to estimate quantitatively the blast wave pressures from a gas explosion using flame propagation velocities.
