摘　　要：应用有限时间热力学的方法,建立一类不可逆埃里克森热机的模型,探讨分析存在热阻、热漏损失、回热损失等不可逆性的埃里克森热机的输出功率与效率的优化性能,推导出热漏损失满足温差幂指数传热规律时热机的功率与效率间的优化关系,所得可为埃里克森热机的模拟设计提供些参考.Using finite time thermodynamics,a model of a class generalized irreversible Ericsson heat engine is set up,the optimal performance of Ericsson heat engine with thermal resistance,heat leak and regenerative loss are studied. The power output and thermal efficiency of a finite- time optimized Ericsson heat engine are studied. The optimal relation between the power and efficiency under heat leak by general heat transfer law is derived. The conclusions obtained here may provide the observed performance of a real heat engine and some new theoretical guidance for the manufacture and the optimal design of two- heat-source engines.
