Research Abstract

In Ocean development, many cylindrical shape structures are in use. These structures are subjected to many external forces. Especially, the lift force induced by the shedding vortices cause the vibration of the structures. One of thesolutions to suppress vibrations is to attach appendages on structures. However, it may happen that such appendages increase vibrations in some situations. In this research, some experiments were carried out to reveal the influence of the motion and flow field around the structure with the appendages. Then, numerical simulation method was developed to easily modify an appendage’s shape and simulate its performance in different circumstances.
