... Engineering, Seoul National Univ., Seoul, Korea The present study aims to investigate the free surface effects on a conventional screw propeller and shaft system by open water tests with submergence depth variations. The force and moment on the propeller were measured, and the types of ventilation were...

... Hydrodynamic lifting bodies operating in close proximity to the free surface can experience adverse effects such as dynamic load fluctuations and ventilation. Operating in waves may amplify the effects by providing external excitation to a lifting body's structure. Hence, the objective...
