摘要 为研究水泵水轮机在水泵工况时不同操作条件下的水力不稳定性,应用计算流体动力学软件Fluent分别对水泵水轮机三维全流道的设计工况、大流量工况和小流量工况进行非定常计算,同时监测了蜗壳进口、转轮与活动导叶之间、转轮与顶盖之间以及尾水管处的压力脉动.结果表明:水泵水轮机在水泵工况下压力脉动幅值最大的位置位于转轮与活动导叶之间的无叶区,转轮与顶盖之间的压力脉动次之,而蜗壳和尾水管处的压力脉动则比较小;在设计工况下压力脉动幅值最小,并且越偏离最优工况压力脉动的幅值越大;位置不同,影响水力稳定性的主频也不相同,转轮与活动导叶之间压力脉动的主频为叶片通过频率,转轮与顶盖之间的压力脉动的主频为转频的倍数,尾水管处压力脉动同时受叶片通过频率和低频的影响,而蜗壳进口处的压力脉动则主要受低频影响.

Abstract: To study the hydraulic instability of a pumpturbine at the pump mode under different working conditions, the threedimensional, unsteady flow in the whole passage of the pumpturbine was conducted by using computational fluid dynamics softwareFluent under the optimal, low and high flow rate conditions. The pressure fluctuations were monitored respectively at the inlet of spiral casing, in the interface of runner and guide vanes, and in the space between head cover and runner, as well as in draft tube. The results show that a larger pressure fluctuation can be found in the interface of runner and guide vanes and in the space between the runner and head cover, while the pressure fluctuation is lower at the inlet of the spiral casing and in the draft tube. The pressure fluctuation is the smallest under the optimal condition; the larger the working condition deviates from the optimal one, the more considerable the fluctuation is. The dominant frequency of pressure fluctuation depends on the locations monitored. The dominant frequencies are integer multiples of the blade passing frequency and the runner rotational frequency in the interface of runner and guide vanes and in the space between runner and head cover, respectively. However, the dominant frequencies of the pressure fluctuation at the inlet of the spiral casing and in the draft tube are mainly related to lowfrequency components.
