| Abstract: | Finite time thermodynamics is applied to analyze the performance of an endoreversible intercooled regenerated Brayton cycle coupled to constant temoerature heat reservoirs. The expressions of dimensionless power output and efficiency are deduced. The intercooled pressure ratio is optimized for maximizing the cycle power output and efficiency. The influences of the effectivenesses of the intercooled exchanger, the regenerator, and the hot-side and cold-side heat exchangers on the performance of the Brayton cycle are analyzed by detailed numerical examples. |
