摘要
用有限时间热力学方法建立了一个工作在恒温热源TH、TL之间,存在热阻、热漏和再热的定常流空气标准闭式布雷顿循环模型。导出了其功率、效率的一般关系并对其进行优化,得到循环的基本优化关系;分析了在傅立叶导热定律下再热对循环最优性能的影响。
Performance analysis and optimization of an air- standani reheat endoreverslble Brayton engine cycle with heat- resistance and heat leakages has been performed by using finite - time thermedynamices.The analytical formulae about power and efficiency of this engine cycle, as well as the relationship between the optimal power output and optimal efficiency are also derived.The effects of reheat on the optimal performance under the linear heat transfer law are analyzed.
