有限时间热力学提出之后,对受热阻影响的卡诺循环已有较深入的研究,而对热阻影响下的布雷顿循环则研究较少,至今尚未求出其基本优化关系。本文由新近发展的两有限热源内可逆循环理论,导出受热阻影响的布雷顿循环的基本优化关系,并揭示其主要特征。 After the finite-time thermodynamics was proposed, the Carnot cycle, which is affected by the thermal resistance, has been studied in depth. However, the Brayton cycle under the influence of thermal resistance has been studied to a lesser extent. So far, no fundamental optimization relationship has been found. Based on the newly developed reversible cycle theory of two finite heat sources, this paper derives the basic optimization relationship of the Brayton cycle affected by thermal resistance and reveals its main features.
