| Abstract: | The performance optimization of an endoreversible Braysson cycle with heat resistance losses in the hot and cold side heat exchangers is performed by using finite time thermodynamics. The relations between the power output and the temperature ratio, between the power density and the temperature ratio, as well as between the efficiency and the temperature ratio of the cycle coupled to constant temperature heat reservoirs are derived. Moreover, the effects of the thermal conductance distribution of hot and cold side heat exchangers, and the dimensionless working fluid temperature ratio on the power output, the power density and the thermal efficiency are studied by detailed numerical examples. |
