Optimal performance of an endoreversible three-mass-reservoir chemical pump with diffusive mass transfer law

The performance of an isothermal endoreversible three-mass-reservoir chemical pump, in which the mass transfer obeys diffusive law, is analyzed and optimized in this paper. The relation between the coefficient of performance and the rate of energy pumping of the isothermal chemical pump is derived by using finite-time thermodynamics. Moreover, the optimal operating regions and the influences of some parameters on the performance of the cycle are studied. The results obtained herein can provide some new theoretical guidelines for the optimal design of a class of apparatus such as mass exchangers, and electrochemical, photochemical, and solid-state devices, as well as fuel pumps for solar-energy conversion systems.
