Features of distribution of spherical shock waves in a heterogeneous medium with a chemically active gas phase

In this paper we present a solution of the model problem on the interaction of spherical shock waves with a heterogeneous layer located near a plane surface. The heterogeneous layer is a two-phase medium consisting of solid particles and a reactive gas phase. The gas phase composition is close to the composition of gaseous products of pyrolysis of forest combustible materials. It has been shown that oxidation reaction of carbon oxide leads to an accelerated rise in temperature and pressure in the gas phase and contributes to an increase in the velocity of propagation of the shock wave in a heterogeneous medium.
