| 摘 要： | 由于轮毂封严气将会对涡轮的流场结构和气动性能产生一定的影响,采用数值模拟研究了不同封严气流量条件下轮毂缘板进口圆角半径对涡轮气动性能和内部流动结构的影响.结果表明,圆角半径的改变导致封严腔内部的流动、封严气在涡轮通道中的传播轨迹以及涡轮通道涡的发展发生改变,进而使涡轮级的载荷系数、反力度和流量系数的分布发生变化,最终影...

| Abstract: | As the seal gas on the hub would produce certain influence on the flow field configuration and aerodynamic performance of a turbine,a numerical simulation method was used to study the influence of the hub flange plate inlet fillet radius on the aerodynamic performance and inner flow configuration at different seal gas flow rates.The research results show that any change of the fillet radius can lead to a change in the seal gas flow in the seal chamber and its transmission trajectory in the passages of the t... |
