Superadiabatic combustion with reciprocating flow in a porous medium has been investigated through experiments and a numerical calculation. In the system, an extremely low-heat-content gas flows into the porous medium, where the flow direction reverses regularly. By means of the reciprocating flow system, the combustion gas enthalpy is effectively regenerated into an enthalpy increase in the mixture through the porous medium, which provides heat storage. The results have shown that the maximum temperature is about 10 times higher than the theoretical one of an ordinary flame in free space. The heating value of the mixture is 128 kJ/M^3, which is equivalent to the temperature increase of about 98 K. Furthermore, through an asymptotic analysis, it is revealed that the maximum temperature is dependent on the overall activation energy, the pre-exponential factor, the Reynolds number and the heating value.
