卡诺热机的最佳利润与效率间的关系

The Relationship between Carnot Heat Engine Maximum Profit and Efficiency

本文导出牛顿定律系统卡诺热机的最佳利润与效率间的关系,并得到最大利润时的效率界限。其结果包含了最大功率和最小熵产率(也即最小损失)两种特例。籍此,作者首次提出了有限时间经济分析和有限时间经济性能界限的概念,为统一现代热力学的各分支研究开拓了方向。

This paper provides a derivation of the relationship between the maximum profit and efficiency for a Carnot heat engine of Newton's law system and gives the efficiency boundary at the maximum profit point.The results obtained include two specific examples featuring a maximum power output and minimum entropy production rate (namely,minimum exergy loss). Based on this, the autho(?)s for the, first time have put forth the conception of a finite time exergy economic analysis and finite time exergy economic performance boundary, which will pave the way for an unified study of the various branches of modern thermodynamics.
