摘要
应用有限时间热力学理论,对一类二热源热机作了统一的描述,导出以理想气体为工质的二热源热机的输出功率与效率间的优化关系,并讨论了回热损失和回热时间对输出功率和效率的影响.所得结果具有普遍意义,可为斯特林热机。
By using Finite time thermodynamic theory,unified description of a class of two heat source engines is achieved.The optimal relation between the power output and efficiency of the class of two heat source engines using an ideal gas as the working fluid is derived,and the influence of regenerative loss and regenerative time of the power output and efficiency is discussed.The results obtained here have general significance.They may provide some new theoretical guidance for the optimal design and the selection of optimal operating parameters of a class of two heat source engines,such as Stirling heat engines,Ericsson heat engines,and so on.
