摘　　要：在原有的不可逆联合动力循环模型的基础上,建立了一个存在热阻、热漏、补燃、内不可逆性的定常流联合卡诺热机循环模型。研究其在补燃作用下的功率和效率特性并对其进行优化,导出功率、效率的基本优化关系,分析了补燃对最优性能的影响。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.
