| Abstract: | The new model of an irreversible gas Stirling heat engine is set up,in which the influence of finite heat capacities of external reservoirs,heat resistance,regenerative losses and the internal irreversibility inside working substances are taken into account.By using the method of finite-time thermodynamics, the optimal expression between the power output and efficiency is derived.Moreover,the maximum power output and other optimal performance parameters are obtained.The results obtained here are more general than the related conclusions presented in the literatures and can provide some theoretical guidance for the manufacture and optimal design of real Stirling heat engine. |
