摘　　要：本文运用有限时间热力学(FTT)理论,导出了恒温热源条件下闭式燃气轮机不可逆中冷循环功率、效率和功率密度的解析式,分别优化了循环最优功率和功率密度时各换热器热导率分配、中间压比和总压比,并比较了相应性能。By using finite-time thermodynamics（FTT） theory,the analytical formulae of power,efficiency and power density for an irreversible closed intercooled gas turbine cycle coupled to constant-temperature heat reservoirs are derived.The heat conductance distribution of the heat exchangers,the intercooling pressure ratio and the total pressure ratio are optimized by taking the power and the power density as the optimization objectives,respectively.Comparison between the optimization performances of the power and the power density is carried out.
