建立受传质不可逆性、质漏以及内部耗散等多种不可逆性影响的一类广义不可逆四库等温化学势变换器的新循环模型,用有限时间热力学或热力学优化理论导出了循环的泵能率和性能系数间的基本优化关系,得到了最大性能系数及相应泵能率和最大泵能率及相应性能系数.分析了各不可逆性对循环性能的影响,结果表明质漏对化学势变换器性能有定性和定量的影响,而内部耗散仅有定量的影响.所得结论可为电化学、光化学、质量交换器及固态设备等的参数优化和性能改善提供新的理论指导.
A new cyclic model of generalized irreversible four-compartment isothermal potential converter based on irreversible influences such as mass transfer irreversibility, mass leakage and internal dissipation is established. The cyclic pump energy rate is derived by finite-time thermodynamics or thermodynamic optimization theory And the coefficient of performance, the maximum coefficient of performance, the corresponding pump rate, the maximum pump rate and the corresponding coefficient of performance are obtained.The influence of each irreversibility on the cycle performance is analyzed.The results show that the qualitative and quantitative properties of the chemical potential converter are qualitatively determined And quantitative effects, while the internal dissipation has only a quantitative effect.The conclusions can provide new theoretical guidance for parameter optimization and performance improvement of electrochemical, photochemical, mass exchangers and solid-state equipment.
