Simulation of Convective Detonation Waves in a Porous Medium by the Lattice Gas Method

摘要

"Gas-film" convective detonation in a rigid porous medium is considered. The motion of the gas phase is described by a discrete stochastic lattice gas model taking into account the real laws of friction and heat exchange between the phases. The reaction kinetics was specified so that the characteristic time of combustion corresponded to experiment. The model simulates the main characteristics of the phenomenon: a non-flat (irregular) wave front, smooth increase in the pressure averaged over the charge cross section, friction-dominated mean flow, slow cooling of combustion products after completion of the reaction.
