摘　　要：用热力学方法研究了三级闭式回热再热中冷燃气轮机循环的效率、功率和中间压比性能,分析了变温热源条件下中冷回热再热燃气轮机循环性能,通过数值计算得到了输出功率最大时高低温侧各换热器的热导率最佳分配和最佳中间压比,优化了总压比,得出了双重最大功率.Finite - time thermodynamics was applied to analyze the characteristics of the dimensionless cycle power output, the efficiency and the optimal intercooling pressure ratio of an irreversible closed intercooling re- heating regenerated Brayton cycle coupled to constant - temperature heat source. The power optimization for a re- al closed intercooled reheating regenerated Brayton cycle coupled to variable - temperature heat reservoirs was studied by the same method. The irreversibilities involving the heat resistance in the four heat exchangers （the hot -side and cold -side heat exchangers, the regenerator and the intercooler）, the irreversible compression and expansion losses in the compressor and the turbine, and the pressure in the piping were taken into account in the analysis.
