Abstract
ABSTRACT This study addresses the alteration of buoy dynamics through the attachment of rotatable hydrofoils, thereby enabling a virtual mooring capability. Buoys equipped with this configuration are referred to as Virtual Mooring Buoys (VMB). The aim of this study is to alter the dynamic properties of the buoy by installing a rotatable hydrofoil. The research focuses on the effects of both steady and unsteady dynamics of the rotatable hydrofoil. Therefore, in order to realise the virtual mooring function, CFD numerical simulation and scale model experiment are used to analyse the hydrodynamic performance of the buoy when it dives in the target waters at the maximum diving speed of 0.3 m/s. A hydrofoil with a high lift-to-drag ratio suitable for the VMB has ultimately been designed. The hydrofoil designed for the VMB in this study fulfils the functional requirements of buoy virtual mooring.
