Simulation of Filtrational Gas Combustion Processes in Nonhomogeneous Porous Media

摘要

A one-dimensional two-temperature model of a combustion front moving with filtration of a fuel gaseous mixture in chemically inert porous media with discontinuous thermophysical parameters is investigated from numerical standpoint. From the algorithmic viewpoint, the emphasis is on new applications of two-level explicit and semi-implicit difference schemes with moving adaptive grids. From the angle of physical features of the processes under consideration, the bulk of attention is focused on aspects of combustion front stabilization, which is important in some technical applications.
