Structure of stationary waves of filtration combustion of gases in an inert porous medium

The structure of stationary waves of filtration combustion of gases in an inert porous medium was considered. Temperature profiles of the porous medium, the concentration of gas and missing component was approximated by exponential and polynomial functions in the areas of heating, combustion and internal relaxation. The formulas for the maximum gas temperature, the ignition temperature and their origin, as well as the coordinates of the maximum reaction rate, and the inflection point in the temperature profile of the porous medium were obtained. To determine the velocity of the wave the ratio parameters were determined. (author)
