| Abstract: | This paper investigates the low-velocity filtration combustion of lean methane-air mixtures occurring in inert packed beds by using a modified one-temperature model. An order-of-magnitude estimate is provided for the scaling analysis, and analytical coupled solutions are proposed for the theoretical analysis. Some characteristic parameters, such as the combustion wave velocity, the flame speed and the peak flame temperature, are predicted. Analytical results have been compared with the related experiments and other existed theories. |
