The finite time thermodynamic performance of an irreversible closed gas turbine regenerated cycle with coustant-temperature heat reservoirs is stydied. The relations between power output, efficiency and pressure ratio of the cycle are derived with the irreversibilities of heat resistance losses in hot- and cold-side heat exchangers and regenerator and the nonisentropic losses in compressor and turbine. The conclusions, which are different from the conventional ones, are that the power output of the cycle is strongly dependent on the effectiveness of the regenerator, and there exsists an optimal matching among the effectivenesses of the two heat exchangers and the regenerator.
