摘要
调整质量流率和沿通流路径压力损失分配可以优化回热式燃气轮机循环的热力学性能。分析表明 ,功率输出相对于燃料流率或任意一个压力损失有一个最大值 ,最大功率输出对总压比有附加最大值。
In this paper we show that the thermodynamic performance of a regenerative gas turbine power plant can be optimized by adjusting the mass flow rate and the distribution of pressure losses along the flow path.Also,we show that the power output has a maximun with respect to the fuel flow rate or any of the overall pressure drops and the maximized power output has additional maximum with respect to the overall pressure ration and overall temperature ratio.The numerical example shows the effect of regenerator effectiveness on the power output and heat conversion efficiency.
