本文对通过三个轴流式诱导轮的空化流进行了完整的三维数值模拟和实验研究。这些诱导轮由前缘叶尖叶片角β1T = 8°、10°和13°来确定。数值和实验研究是在巴黎国立高等工程技术学校（ENSAM - Paris center）的流体内部能量与力学实验室（LEMFI laboratory）进行的。首先对空化状态建模以及本文计算所使用的空化均相模型进行了综述。数值模型基于多相流方程与瑞利 - 普莱斯方程的简化版相结合，该简化版方程用于预测气泡复杂的生长和溃灭过程。由于空化导致的质量传递是液相和气相连续性方程中的源/汇项。
The paper presents full 3D numerical simulations and experimental investigations of the cavitating flow through three axial inducers. These inducers are identified by the tip blade angle at the leading edge β 1T =8, 10, and 13 deg. The numerical and experimental investigations were carried out at the LEMFI laboratory (Laboratoire d'Energetique et de Mecanique de Fluides Interne) of the ENSAM-Paris center (Ecole rationale Superieure d'Arts et Metiers). A review of the cavitating regime modeling and the cavitation homogeneous model used for this paper's calculations is first presented. The numerical model is based on a combination of the multiphase flow equations with a truncated version of the Rayleigh-Plesset model predicting the complicated growth and collapse processes of bubbles. The mass transfers due to cavitation are source/sink terms in continuity equations of the liquid and vapor phases
