| Abstract: | Taking thermal efficiency as optimization objective, this paper applies finite-time thermodynamics to optimize the intercooling pressure ratio and the heat conductance distribution of hot- and cold-side heat exchangers, intercooler and regenerator of an endoreversible intercooled regenerated Brayton cycle coupled to constant-temperature heat reservoirs. Double-maximum efficiency is obtained by further optimizing the total pressure ratio. The effects of some important parameters on the optimal results are analyzed by detailed numerical examples. |
