Study results indicate that hybrid cycles with micro gas turbine-molten carbonate fuel cells have a higher power generating efficiency in the topping arrangement, while the bottoming arrangement exhibits good off-design behavior. 结果表明:熔融碳酸盐燃料电池/微型燃气轮机顶层联合循环系统具有较高的发电效率,而底层循环具有良好的变负荷特性。
The unsteady flow in a draft tube of Francis turbine under the off-design operation is produced by the dynamic behavior of a helical vortex rope with the dead core. 混流式水轮机在非设计工况点下运行时,尾水管内部的非定常流动是由死水域和螺旋涡带的动态行为引起的,尾水管上部的螺旋涡带旋转引起流动的基频脉动。
