| Abstract: | The steady flow endo-irreversible Carnot engine with heat resistance and heat leak is in-vestigated by finite time thermodynamics in this paper. The optimal relations between power and isentropic temperature ratio exponent, and between efficiency and isentropic temperature ratio expo-nent are derived , by which the optimal relation curve between power and efficiency can be obtained. The related conditions are also given. Finally, these relations are analyzed and discussed , some useful results are drawn. |
