提出了一种基于多孔介质中往复流超绝热燃烧的新型热光伏发电系统，并对其进行了数值模拟研究。多孔介质由薄泡沫陶瓷板和一对多孔石英玻璃板组成，这对多孔石英玻璃板垂直于流动方向填充在绝缘流动管道中。通过往复流燃烧系统的能量再循环，泡沫陶瓷温度变得比理论（绝热）火焰温度高约两倍，仅使用少量的燃烧热。从泡沫陶瓷板发出强烈的辐射能量。其中，长波长成分被多孔石英玻璃吸收并再生以预热工作气体。另一方面，短波长成分通过多孔石英玻璃。约48%的燃烧热转化为短波长范围内的辐射能，这对（GaSb）TPV的制备是有用的。
A new thermophotovoltaic (TPV) power generation system has been proposed on the basis of reciprocating‐flow super‐adiabatic combustion in porous media and has been investigated through numerical simulation. The porous media consists of a thin foam‐ceramic plate sandwitched by a pair of porous quartz glass plates packed perpendicular to the flow direction in an insulated flowing‐duct. By energy recirculation through the reciprocating‐flow combustion system, the foam‐ceramic temperature becomes about two times higher than the theoretical (adiabatic) flame temperature, using only a small amount of combustion heat. Strong radiant energy is emitted from the foam‐ceramic plate. Of those, long wavelength components are absorbed by the porous quartz glass and are regenerated to preheat working‐gases. On the other hand, short wavelength components pass through the porous quartz glass. About 48% of the combustion heat is converted into the radiant energy in a short wavelength range which are useful for (GaSb) TPV p...
