摘要
用有限时间热力学方法优化恒温热源条件下闭式中冷回热燃气轮机循环的生态学性能,计入工质与高低温侧换热器、回热器以及中冷器之间的热阻损失、压气机内不可逆压缩和涡轮内部不可逆膨胀损失,导出了循环生态学函数解析式,通过数值计算优化各换热器热导率分配以及中间压比和总压比,得到了循环最优生态学性能。
Einite- time thermodynamics is applied to optimize the Ecological nerformanee of an irreversible closed intereooled regenerated gas turbine cycle coupled to constant- temperature heat reservoirs and with both external irreversibilities（the heat resistance between the working fluid and the hot- and eold - side heat exchanger, the regenerator and the intereooler）and intermal irreversibilities（ the irreversible compression process in compressors and the irreversible expansion process in turbines）. The analytical formule of eeological function of the cycle are obtained and the optimal ecological performance is obtained by optimizing the distribution of heat eonduetanees among four heat exchangers, the total compression ratio and the intereooling pressure ratio by detailed numerical examples.
