本研究旨在揭示含有空气的流入流对高速诱导轮的内部流动和性能的影响。基于剪应力传递湍流模型和欧拉-欧拉非均相流模型，在不同空气体积分数条件下进行了数值计算。在气水两相条件下进行了外特性、空化性能和可视化实验。结果表明，小流量工况下含空气来流对诱导轮水头下降的影响大于大流量工况。适当的空气体积分数有利于诱导轮空化性能的提高。随着空气体积分数的增加，诱导轮轴向和径向的压力梯度逐渐减小，诱导轮的增压性能也变差。流道中轮毂附近的流动变得杂乱，湍流能量增大。空气主要集中在流道中的前缘边缘和轮毂附近的低叶片高度区域。随着空气体积分数的增加，空气在周向、径向和轴向方向上膨胀。
This study is to reveal the influence of incoming flow containing air on the internal flow and performance of a high-speed inducer. Numerical calculations were performed herein under different air volume fraction conditions based on the shear-stress transport turbulence model and the Eulerian–Eulerian heterogeneous flow model. The external characteristic, cavitation performance and visualization experiment were conducted under the air–water two-phase condition. As a result, the effect of incoming flow containing air under small flow rate condition on the decline of the inducer head was larger than that under large flow rate condition. The proper air volume fraction was beneficial to the improvement of the inducer cavitation performance. As the air volume fraction increased, the pressure gradients in the axial and radial directions of the inducer gradually reduced and the supercharging performance of the inducer also worsened. The flow near the hub in the flow channel became messy, and the turbulence energy increased. The air mainly concentrated in the leading edge rim and the low blade height region near the hub in the flow channel. The air expanded in the circumferential, radial and axial direction as the air volume fraction increased.
