摘要
研究了有限热源条件下工质与热源间传热规律服从混合热阻形式时热机的有限时间热力学性能 ,讨论了循环的最优构型及最优功率与效率间的优化关系 ,所得结果对实际热机的设计工作具有一定的指导作用。
The finite time thermodynamic performance of a heat engine is studied under the condition of finite heat source when the law of heat conduction between operation medium and heat source obeying the mixed heat resistance. The optimal configuration and the fundamental relation between optimization power and efficiency of the cycle are derived. The results can provide some theoretical guidance for the design of practical heat engine.
