The Influence of Heat Leak by Generalized Heat Transfer Laws on Optimal Performance of a Class Stirling Heat Engine

In this paper, the model of a class generalized irreversible Stirling heat engine is set up, we report a study on the optimal performance of an irreversible Stirling heat engine with thermal resistance, heat leak and regenerative loss using finite time thermodynamics. The optimal relation between the power and efficiency under heat leak by general heat transfer law is derived. The effect of heat leak and regenerative loss with various value on performance of heat engine is discussed.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.
