Abstract: Cavitation jet has been widely used because of its advantages in high efficient energy and zero pollutions. However,the complexity of its structure and hydrodynamics limit its applications in industries. In order to better understand and study the characteristics of cavitation jet flow field, numerical simulation of cavitation jet flow field,cavitation models,numerical calculation method and the characteristics of cavitation flow field were discussed in this paper. The numerical models,including cavitation models,turbulence models and multiphase model,were analyzed. Applications of Lagrangian and Eulerian numerical methods used in cavitation jet were compared,and the computation requirements in cavitation jet flow field. The influences of different factors on cavitation jet flow field were discussed. Three directions of future research were prospected.
