Abstract

The theory of finite time thermodynamics is used in the analysis of an endoreversible closed intercooled regenerated Brayton cycle coupled to variable temperature heat reservoirs.The analytical formula about power density of the cycle is derived.The effects of thermodynamic parameters of the cycle on the power density are analyzed by numerical calculation.The advantages and disadvantages are obtained via the comparison of the main parameters of cycle at the maximum power and maximum power density points.
