对多孔介质中往复流动的超绝热燃烧进行了数值计算。在该系统中，热含量极低的可燃气体流入多孔介质，在多孔介质中流动方向规则反转。通过往复流动系统，燃烧气体的热能通过多孔介质有效地再生为可燃气体的热能增加，从而提供储热。结果表明，多孔介质中的火焰温度比自由空间中普通火焰的理论温度高13倍。可燃气体的热值约为65kJ m−3，仅相当于温升50K。
Superadiabatic combustion with reciprocating flow in a porous medium has been investigated through a numerical calculation. In this system, a combustible gas with an extremely low heat content flows into the porous medium, where the flow direction reverses regularly. By the reciprocating flow system, the combustion gas enthalpy is effectively regenerated into an enthalpy increase in the combustible gas through the porous medium, which provides heat storage. The results have revealed that the flame temperature in the porous medium is 13 times higher than the theoretical one of the ordinary flame in free space. The heating value of the combustible gas is about 65 kJ m−3, which is equivalent to a temperature increase of only 50 K.
