| 摘 要： | 应用CFD技术模拟计算了双流道式泵包括叶轮及压出室在内的全三维湍流场,证实了双流道压出室内流动分布不均匀并随叶轮转动而变化、叶轮转动到不同位置时泵的效率和扬程不同、基圆大小不同时压出室第Ⅰ断面内流场分布存在显著差别。计算结果有助于深入了解双流道叶轮压出室内部流动机理,对双流道叶轮压出室的水力设计提供参考。

| Abstract: | Using CFD to simulate and calculate the 3D turbulent flow in a double channel impeller and pump case is introduced.Make sure flow is different in the the pump base.The flow changes with impeller running The efficiency and lift are variable at different impeller position.The variety of flow in first section of pump case changes along with the variety of base circle diameter.The results provide an understanding of the flow in the double channel impeller and pump case to improve the hydraulic design. |
