广义热力学优化理论是热科学与技术领域的研究热点之一.本文首先回顾了有限时间热力学、熵产生最小化理论、理论、广义热力学优化理论的产生与发展,深入剖析了上述热学优化理论的物理内涵及其相互间异同点,然后从传热过程、传质过程、电容器充电电路和经济贸易过程等不可逆过程动态优化研究方面介绍了广义热力学优化理论的研究进展,重点比较了熵产生最小化理论和理论在传热传质过程优化中的异同点,最后指出除在研究对象范围和研究内容方面进一步拓展与细化外,追求物理模型的统一性、优化方法的通用性和优化结果的普适性是广义热力学优化理论的另一重要发展趋势.
Generalized thermodynamic optimization theory is one of the research hotspots in the field of thermal science and technology.Firstly,the emergences and developments of finite time thermodynamics,entropy generation minimization,entransy theory and generalized thermodynamic optimization are reviewed in this paper,respectively.Besides,the physical connotations of the above thermal optimization theories are analyzed in detail,and their similarities and differences are also indicated.Secondly,the research progress of the generalized thermodynamic optimization theory is introduced from the aspects of dynamic optimizations of several irreversible processes including heat-transfer,mass-transfer process,capacitor charging circuit,and economical trade processes.The similarities and differences between the entropy generation minimization theory and the entransy theory in the optimization of heat and mass transfer processes are compared in detail.Finally,in addition to the expansion of the research subjects and the refinement of the research contents,the pursuit of the universal of the physical models,the unity of the optimization methods and the generalization of the optimization results is another important development trend of the generalized thermodynamicoptimization theory.
