| Abstract | TK730; 固液两相流条件下半开式叶轮离心泵中颗粒冲击、泄漏涡发展和颗粒轨迹之间存在紧密交互作用,导致过流部件的磨损行为复杂多变.该研究结合双向耦合欧拉-拉格朗日方法和颗粒磨损Finnie模型,对不同颗粒体积浓度下半开式叶轮离心泵固液两相流场进行求解,分析了颗粒体积浓度对泄漏涡结构特征、颗粒运移轨迹和磨损特性的影响,揭示了颗粒体积浓度、叶顶间隙泄漏涡和过流部件表面磨损规律的关联机制.结果表明:随着颗粒体积浓度的增加,颗粒的频繁撞击加剧了叶片压力面进水边和后盖板磨损程度,叶片吸力面出水边的磨损范围向进水边方向延伸;颗粒体积浓度小于1％时,颗粒的轴向运动和叶顶间隙泄漏涡的阻碍作用导致颗粒易与叶片前缘靠近叶根处和吸力面出水边靠近叶顶的区域发生撞击,诱发严重磨损,且呈现点状磨损;当颗粒体积浓度大于3％时,叶轮后盖板的整体磨损强度大于叶片,颗粒体积浓度的增加造成流入叶顶间隙层的颗粒数增加,颗粒对叶顶间隙泄漏涡的冲击导致涡流的破碎、分离、再融合,加剧不稳定流动,泵的扬程和效率均明显下降.该研究可为固液两相半开式叶轮离心泵优化设计和安全稳定运行提供理论参考. |
