| Abstract: | An irreversible model for Stirling engine which considers thermal resistance and thermal leakage as well as regenerative heat losses was established by using finite time thermodynamic theory.The expressions of Stirling engine performance were derived by using the maximum output power,maximum efficiency and ecological optimization criterion.And the three optimization criterias were compared under conditions that the heat leak coefficient and heat exchanger effectiveness were considered.The results show that ... |
