The propagation of reacting blast waves through inert particle clouds

The purpose of this study is to investigate the gasdynamic aspects of blast waves in a combustible gas containing small solid suspended particles which are chemically inert. The effects of suspended particles on the reacting blast waves are examined under the assumption that the velocity and temperature of the particles are equal to those of the gas. The two-phase flow equations for the explosion are solved for the spherical case by a series expansion method in the dimensionless chemical heat release. The wave structures and dimensionless propagation velocities are shown. It is found that the suspended particles cause more rapid decay in the propagation velocity of the blast wave by providing heat and momentum sinks.
