回顾总结了热力学与传热学共性理论基础研究的系列成果,从正视热力学第二定律、“熵商产”理论在实际应用中存在的问题入手,以势能理论为依据,用相对环境平衡态的势能为基准态势能定义了能量中的有效能和无效能.这种定义具有与“(火用)”相同的性质,又能从定义式直接写出有效能函数的表达式.继而利用热力学第一定律方程,推导出了普适的有效能方程、有效能率方程,并与熵方程、(火积)煨耗散方程和(火用)方程进行了比较.前者方程各项都只与状态有关,都能独立计算出来,而后三个方程都有一项与不可逆过程有关的补缺项.把有效能率方程应用于传热过程,导出了传热效率的表达式;应用于实际热机系统,导出了传热与热力耦合系统的输出功率、输入热流率、效率、换热器传热系数以及热源参数之间的关系,并举例应用于系统优化设计.本文构建的热力学和传热学共性理论,为热机与换热器耦合进行热力系统综合分析和协调优化提供了理论基础.“,”This paper reviews and summarizes the results of the basic research on the common theory of thermodynamics and heat transfer.Starting with the problems of the second law of thermodynamics and the “entropy generation” theory in practice, based on the theory of potential energy, the effective energy and the inefficient energy are defined on the basis of the relative equilibrium state.This kind of definition has the same property as “exergy”, and the expression of effective energy function can be deduced directly from it.Then, by using the first law of thermodynamics, the universal effective energy equation and effective energy rate equation are deduced and compared with the entropy equation, the entransy dissipation equation and the exergy equation.Each term of first two equations is only related to the state so that can be independently calculated, and the last three equations all need an adding term related with irreversible process.The effective power rate equation is applied to the heat transfer process, and the expression of heat transfer efficiency is deduced.It is also applied to the actual heat engine system which is a coupling system of heat transfer and thermodynamics, and the relationship between output power, input heat flow rate, efficiency, heat transfer coefficient of the heat exchanger, and heat source parameters is deduced and applied to system optimization design.The common theory of thermodynamics and heat transfer, which is constructed in this paper, provides a theoretical basis for the analysis and optimization of the thermodynamic system which is coupled by heat engine and heat exchanger.
