✦ Synopsis

This paper describes an application of "nite-time thermodynamics to optimize the power output of endoreversible intercooled Brayton cycles coupled to two heat reservoirs with in"nite thermal capacitance rates. The e!ects of intercooling on the maximum power and maximum-power e$ciency of an endoreversible Brayton cycle are examined. With appropriate temperature ratios of turbines and compressors being used, the maximum power output of an endoreversible intercooled Brayton cycle can be higher than that of an endoreversible simple Brayton cycle without lowering the thermal e$ciency. New diagrams for maximum power, maximum-power thermal e$ciency, and optimum temperature ratios of turbines and compressors are reported.
