摘要:
为了研究导叶角度对轴流泵高效区运行范围的影响，采用CFD和模型试验对不同导叶角度下轴流泵水力性能进行数值模拟计算，并且进行内流场比较分析。结果表明，通过改变导叶角度后，优化导叶在设计和大流量工况下的内部流场更加均匀合理，导叶优化后的轴流泵最高效率为87.53%，与初始导叶方案相比，配优化导叶的轴流泵高效区运行范围扩宽了近1.36倍 。最后通过模型试验对比分析，验证了数值计算的可靠性。研究结果可为提高轴流泵高效区的运行范围提供参考。
Abstract:
In order to study the influence of the angle of the guide vane on the operating range of the high efficiency zone of an axial flow pump, CFD and model test are used to carry out numerical simulation calculations of an axial flow pump with different guide vane angles and to carry out a comparative analysis of the internal flow field. The results show that after changing the angle of the guide vane, the internal flow field of the optimized guide vane is more uniform and reasonable under the design and high flow conditions, and the maximum efficiency of the axial flow pump after the optimization of the guide vane is 87.53%. Compared to the initial guide vane solution, the operating range of the axial flow pump with optimized guide vane is extended by nearly 1.36 times in the high efficiency zone. Finally, the reliability is verified by model test comparison. The research results can provide a reference for improving the operating range of high efficiency areas of axial flow pumps.
