质漏对内可逆四源化学泵性能的影响

Influence of mass leakage on performance of endoreversible four-reservoir chemical pump

建立受传质不可逆性和质漏影响的一类不可逆四源化学泵的新循环模型,分析这些不可逆性对循环性能的影响,导出了循环的泵能率和性能系数间的基本优化关系,同时确定了一些重要参数的最优工作区域和性能界限。

A new cyclic model of a class of four-reservoir chemical pumps affected by the irreversibilities of mass transfer and mass leakage was set up. The influences of these irreversibilities were analyzed. The fundamental optimal relation between the coefficient of performance and the rate of energy pumping of the cycle was derived. Moreover, the optimally operating regions and the performance bounds of some important parameters of the chemical pump were determined.
