| Abstract: | Base on the irreversible combined power cycle model currently available,a universal model of combined Carnot cycle model with finite-rate heat transfer,heat leakage,internal irreversibility and supplemental combustion was developed in this paper.The relationships of power output with efficiency,as well as the optimal power output with efficiency of this model cycle were also derived.The effects of supplemental combustion on the optimal performance were analyzed. |

| Keywords: | combined cycle irreversible carnot heat engine performance optimization supplemental combustion finite time thermodynamics generalized thermodynamic optimization |
