摘　　要：阐明了有限时间热力学优化对传热传质过程和设备的重要意义,从物理学和工程学两个角度综述了传热传质过程和设备的热力学优化研究现状。从优化方法(数值优化和最优控制理论)、优化目标(最小熵产生、最小平均耗热(功)量、最大生产率、最大效率)、优化结果等几个方面重点介绍了蒸馏与分离过程理论循环和工程循环、化学反应器的性能优化问题,探讨了传热传质过程和设备热力学优化的发展趋势,指出了具有完全可控换热器、序接换热器以及综合了热机的换热器网络的非绝热蒸馏是近期非绝热蒸馏热力学优化研究的主要发展方向。The important significance of finite-time thermodynamic optimization to a heat and mass transfer process and relevant equipment has been expounded.From the standpoint of physics and engineering a broad overview is given of the present status of research in the above-mentioned arena.With focused attention a description is given of the performance optimization of theoretical and engineering cycle concerning distillation and separation processes as well as the performance optimization of chemical reactors from the following aspects: optimization methods(numerical optimization and optimal control theory),optimization objectives(minimum entropy generation,minimum average heat(work) consumption,maximum productivity,maximum exergy efficiency) and optimization results.Also explored is the development trend of the thermodynamic optimization of the heat and mass transfer process and relevant equipment.It is noted that the major development direction of the current non-adiabatic distillation thermodynamic optimization consists in the non-adiabatic distillation equipped with completely controllable heat exchangers,sequential heat exchangers and heat exchanger network incorporating heat engines.
