摘　　要：应用有限时间热力学理论,基于仅考虑传热损失的内可逆往复式Maisotsenko-Brayton循环模型,推导出了循环熵产率和生态学函数等重要参数表达式。通过数值计算,分析与研究了空气饱和器出口温度、循环最高温度和注水流率对循环性能的影响。将内可逆往复式Maisotsenko-Brayton循环与传统往复式Brayton循环进行比较,结果表明内可逆往复式Maisotsenko-Brayton循环性能优于传统往复式Brayton循环性能。Based on an endoreversible reciprocating Maisotsenko-Brayton cycle model with only heat transfer loss,important parameter expressions,such as entropy generation rate and ecological objective function,are derived by using the finite time thermodynamics (FTT) theory.The influences of outlet temperature of air saturator,the maximum temperature of the cycle and the mass flow rate of the water injected to the cycle on cycle performance are analyzed and studied by using numerical examples.The performances of endoreversible recip-rocating Maisotsenko-Brayton cycle and traditional reciprocating Brayton cycle are compared,and the results show that the performance of endoreversible reciprocating Maisotsenko-Brayton cycle is superior to that of tra-ditional reciprocating Brayton cycle.
