Discrete Model of Combustion in a Sample Consisting of Activated and Nonactivated Cells Separated by Gas Dispersed Interlayers

Abstract

An inhomogeneous model of gas-free combustion of a mixture consisting of activated and non-activated cells was proposed. The structure of the combustion wave was studied to suit the scale of heterogeneity, reaction cell size. The influence of gas dispersed layers separating the reaction cells on the burning velocity of a combined mixture was analyzed. The burning velocity dependences at varying effective porosity, effective thermal conductivity, and external heat transfer parameters were constructed.
