| 摘 要： | 根据有限时间热力学理论,在给定各换热器总热导率的情况下,对变温热源条件下等温加热过程修正的不可逆回热式Brayton循环的功率特性进行了优化.研究表明,该情况下全局性的优化结果并不存在.在给定CCC(收敛型燃烧室)和回热器热导率分配的情况下,通过数值计算,得到了最佳的透平出口温度及RCC(常规燃烧室)和低温侧换热器的热...

| Abstract: | According to the theory of finite-time thermodynamics,power output has been optimized for an irreversible regenerated modified Brayton cycle with isothermal heat addition coupled to variable-temperature heat reservoirs with respect to the turbine outlet temperature and the heat conductance distributions of the RCC(Regular Combustion Chamber),CCC(Converging Combustion Chamber),the regenerator and the cold-side heat exchanger for a fixed total heat inventory.The investigation indicates that the global optimiz... |
