Change in the structure of the filtration combustion wave due to a fuel composition change

Transition processes due to a sharp change in the amount of fuel in carbon/inert material mixtures in a filtration combustion wave with superadiabatic heating were studied theoretically and experimentally. It was found that transition from a lean mixture to a rich mixture, in which the thermal wave changes structure from normal to inverse, was accompanied by significant local heating, whereas in the reverse change in the composition, a temperature increase was not observed.
