| 摘 要： | 设计了一副长短叶片各5个间隔布置的离心泵叶轮，应用二维粒子图像速度仪（2D—PIV）成功测试了大流量、设计流量和小流量3种工况下长短叶片同一叶槽内的瞬时流场。测试结果充分揭示了长短叶片叶轮内速度矢量场特征及长叶片吸力面、压力面和短叶片压力面、吸力面相对速度随叶轮半径的变化规律。分析了3种工况下相对速度沿圆周方向的变化规律。

| Abstract: | A five-bladed centrifugal pump impeller with five splitters was designed for the experiment. Detailed 2D-PIV measurements of flow fields about three different fluxes inside the same rotating blade-to-blade passage have been successfully performed in conjunction with the overall pump performance measured separately. The complex internal flow patterns were acquired and the relative velocity varying law near the suction surfaces and pressure surfaces of long blades and the operation sides and opposite sides of short blades were also revealed. Blade-to-blade distributions of the relative velocity about three fluxes were obtained at different radial stations. |
