摘要

An advanced concept has been presented for the thermoelectric energy conversion consisting of porous thermoelectric elements, in which the high power generation is produced due to the steep temperature gradient maintained by the novel combustion control.
A mathematical model exploited here is to give a theoretical foundation and to analyze the combustion phenomena in porous media consisting of thermoelectric materials as well as the electric power generation by Seebeck and Peltier effects. The pronounced feature, in the system, is to be able to regenerate the heat losses by heat conduction, Joule heat by electric current and Peltier heat ejected at the cold junctions for the preheat of combustion.
The analytical results have exhibited the variations of temperature distributions for the major important parameters such as the flow velocity, the heating value of combustible mixture, the thermal conductivity of the thermoelectric elements, the electric power extracted and so forth. The conversion efficiency has been evaluated for the ranges of foregoing parameters of practical interest.
