The objective of this paper is to evaluate the predicted capability of mixture and VOF models for the simulation of unsteady flows around a moving revolution vehicle. In the simulation, the k-ε turbulence model is used along with the transport equation-based cavitation model, in order to simulate the water-exit process, the dynamic mesh technique is applied. Results are shown at non-cavitation and cavitation, respectively, and the transient flow structures and time evolution of pressure distribution are obtained. The numerical results analyze the difference between the capability with VOF and Mixture model, which is very important for the theoretical research and engineering application.
