The present study focuses on the simulation of unsteady ventilated-cavitating flow during the vertical water-exit and water-entry of projectiles with and without exhaust plume. The propulsion exhaust plume gas embedded within the surrounding liquid strongly affects on the wake of flow. For simulation of water-exit and water-entry behavior of the cavitating projectiles which presents aspects of the flow physics such as cavity shape and phase topography of the flow during the processes, a numerical multi-phase homogeneous mixture model is utilized. The model is developed based on the unsteady incompressible Reynolds-averaged Navier-Stokes equations. Preconditioning pseudo-time stepping method is employed to improve the computational efficiency of the model. The results indicate that characteristics of cavity flow induced during water-exit and water-entry primarily depend on the geometry of projectiles and the velocities of flow. In addition, the gas exhaust delays the surface closure of the water-entry cavity that is one of the most important events in later cavity growth.
