Abstract

Cavitation affects the performance of water-jet pumps. Cavitation erosion will appear on the surface of the blade under long-duration cavitation conditions. The cavitation evolution under specific working conditions was simulated and analyzed. The erosive power method based on the theory of macroscopic cavitation was used to predict cavitation erosion. The result shows that the head of the water-jet pump calculated using the DCM-SST turbulence model is 12.48 m. The simulation error of the rated head is 3.8%. The cavitation structure of tip leakage vortex was better captured. With the decrease of the net positive suction head, the position where the severe cavitation appears in the impeller domain gradually moves from the tip to the root. The erosion region obtained by the cavitation simulation based on the erosive power method is similar to the practical erosion profile in engineering. As the net positive suction head decreases, the erodible area becomes larger, and the erosion intensity increases.

摘要

空化会影响水射流泵的性能。在长时间空化条件下，叶片表面会出现空蚀。对特定工况下的空化演化进行了模拟分析。采用基于宏观空化理论的侵蚀功率法预测空蚀。结果表明，采用DCM-SST湍流模型计算得到的水射流泵扬程为12.48m。额定扬程的模拟误差为3.8%。较好地捕捉到了叶顶泄漏涡的空化结构。随着净正吸入压头的降低，叶轮区域出现严重空化的位置逐渐从叶顶向叶根移动。基于侵蚀功率法的空化模拟得到的侵蚀区域与工程实际侵蚀轮廓相似。随着净正吸入压头的降低，可侵蚀面积增大，侵蚀强度增加。
