| Abstract: | The characteristics of the inter-cooling pressure ratio and the heat conductance distributions among the hot-and cold-side heat exchangers, the regenerator and the intercooler at the maximum power of an closed Endo-reversible inter-coooling regeneration Brayton cycle coupled to variable-temperature heat reservoirs was studied with detailed numerical calculations, taking the power as the optimum function, counting in the heat resistance in the hot-and cold-side heat exchangers, the regenerator and the intercooler. The effect of the thermal capacity rate matching between the working fluid and the heat reservoirs on the characteristic of the doulble maximum power was also analyzed. |

| Keywords: | finite-time thermodynamics Brayton cycle inter-cooling regeneration power optimization |
