Abstract
This article summarizes a simulation campaign to study atmospheric ventilation flow patterns, forces, and stability at various speeds. Simulations are based upon cited experiments, and results show good agreement for global forces, cavity shapes, etc. The hydrofoil deceleration process includes three different flow regimes: fully ventilated flow, fully wetted flow, and partially ventilated flow. To obtain the evolution process of the vortex structure, the vortex structure is visualized using the Omega method. The results show that the evolution of the vortex structure mainly includes three types of vortex structures, i.e., a tip vortex, a Karman vortex, and an unstable vortex. The vortex structure is related to the ventilated cavity. Omega can identify weak vortices and strong vortices.
