| Abstract: | The performance of Brayton and Stifling combined cycles with heat resistance and heat leakoge was analyzed based on ecological coeffwient of performance （ECOP） coefficient （ratio of the exergy output to exergy loss） using the finite time thermodynamics. The analysis formulae of ECOP of Brayton cycles with heat resistance and heat leal~oge were derived the relations an~ong them were obtained by numerical examples. The effects of various parameters on the combined cycle performance were analyzed and investigated. |
