摘要： 研究了两热源具有有限热客流率时内可逆定常态卡诺热机在有限时间下的效率与功率之间的关系,就两种不同换热模式在两类约束条件下推导出实际卡诺定常态热机在有限时间内的最大功率与最佳效率之间的相互关系,并对这些新的性能界限做了有益的讨论。

Abstract: In this paper,the power and efficiency of the finite time steady-state heat engine operating between two reservoirs with finite heat-capacity rate are studied.The optimum power and efficiency of the finite time endoreversible Carnot heat engine under two kinds of restraining conditions and operating in two cyclic modes are derived analytically, and some new performance limits of the finite time thermodynamics are discussed.

Key words: endoreversible Carnot cycle, finite time thermodynamics, finite heat reservoir, steady-state engine
