摘　　要：基于低比转速喷水推进轴流泵空化性能重要性的分析,对所设计的低比转速喷水推进轴流泵水力模型在设计流量下进行CFD空化模拟,分析空化特性和空化发生、发展过程,并通过模型空化试验比较验证数值模拟结果。比较表明:设计流量下,模型试验与数值模拟结果相吻合。研究结果为低比转速喷水推进轴流泵空化性能的深入研究提供参考。Based on the analysis on the importance of cavitation for the performance of axial flow water jet pump with low specific speed, cavitation in a designed model pump is simulated with a CFD program at the design flow rate. Cavitation properties, its occurrence and development are analyzed, and numerical simulation results are compared with model test. It is indicated that the numerical simulation was consistent with the model test at the design flow rate.. This research provides a reference for intensive study on cavitation performance of axial flow water jet pumps with low specific speed.
