一类内可逆循环运行的优化

FINITE TIME OPTIMIZATIONS OF AN ENDOREVESIBLE POLYTROPIC CYCLE

本文讨论工作限于有限高低温热源间循环的有限时间热力学过程的优化。这一循环由两个多方过程和两个绝热过程组成,并被广泛地用于实际工作。本文分别讨论了以最大輸出功率、最大效率和最小熵产生率为目标函数运行的优化,井将这些结果与无限熱源条件下优化的结果加以比较。这一模型更接近于实际,结论有较强的指导意义。

In this paper we present a model of vary general applicability. This modle is made up of two polytropic and nwo adiabatic branches and worked between two finit heat reservoirs.The finit time optimizations of the model with maximun power maximun efficiency and maximun entropy production as the objective functions had been carried out, A comparesion between this model and the tarditinal had been illustrated.
