The Effects of Mass Leak and Mass-transfer Irreversibility on the Cyclic Performance of the Chemical Pump

建立不可逆化学泵循环模型,揭示质量传递不可逆性和质量漏对其性能的影响,导出循环的泵能率与性能系数间的优化关系,在此基础上进一步讨论循环的其它优化特性.所得结论可为质量交换器,电化学、光化学、固态设备及燃油泵等设备的优化设计提供新的理论指导.

The model of an irreversible chemical pump is set up and the effects of mass-transfer irreversibility and mass leak on the performances of the chemical pump are revealed. The optimal relation between the coefficient of performance and the rate of energy pumping is derived. On the basis of the optimal relation, we discuss further other optimal performances for the cycle of the chemical pump. The results obtained here can provide some new theoretical bases for the optimal design of a class of apparatus such as mass exchangers, electrochemical, photochemical and solid-state device, as well as fuel pump and so on. 
