Research on characteristics of flow around cavitating body of revolution

FU Hui-ping, LU Chuan-jing, WU Lei (Dept. Engineering Mechanics, Shanghai Jiaotong Univ., Shanghai 200030, China)  
Characteristics of flow around cavitating body of revolution was researched with a single-fluid with variable density approach based on Rayleigh-Plesset equation, what is called mixture model embodied in commercial CFD code Fluent 6.0. The first investigation was on geometrical and drag characteristics of partial cavity around some bodies with distinct head-forms by employing a 2D axisymmetric solver. And the drag reduction mechanism of cavitating flow was probed. The cavitating flow at non-zero angle of attack and supercavity pattern were investigated with a 3D solver. The head-form, which is more incident to cavitation, is found; and the result is in good agreement with relevant experimental dada. Supercavity and double-cavity pattern at zero and non-zero angle of attack were obtained.
