| Abstract: | Finite-time thermodynamics was applied to analyze the characteristic of the cycle dimensionless power output the efficiency and the optimal intercooling pressure ratio of an irreversible closed intercooling regenerated Brayton cycle coupled to constant-temperature heat source. The analytic expressions of the dimensionless power output and the efficiency were deduced. The effects of the e intercooling exchanger and the regenerator on the optimal cycle power output, the optimal cycle efficiency and corresponding intercooling pressure ratio of the Brayton cycle were calculateded. |
