热传递规律对一类二热源机性能的影响

The Effect of Heat Transfer Law on the Performance of a Class of Two-Heat-Source Engines

本文基于较一般的热传递规律,研究传热的不可逆性对一类工作在二热源间的热机性能的影响,导出其最佳传热面积比。并对这类热机在不同热传递规律下的供热率、效率和输出功率等重要参数作了较详细的讨论,获得一些有用的新结论。

Based on a relatively general heat transfer law, the author has studied the effect of the irreversibility of heat conduction on the performance of a class of engines operating between two heat sources. The optimal ratio of heat-conduction areas of engines is obtained by derivation.In addition, the important parameters of the engines under different heat transfer laws, such as heat input rate, efficiency, power output, etc are discussed in detail with some new useful conclusions being presented in this paper.
