Wave force analysis of the vertical circular cylinder by boundary element method

To solve the diffraction of water waves by a bottom-fixed vertical circular cylinder, a numerical analysis by the boundary element method is developed by using linear potential theory. A numerical analysis by boundary element method is based on Green’s theorem and introduced to an integral equation for the fluid velocity potential around the vertical circular cylinder. The numerical results by boundary element analysis are compared with those of MacCamy and Fuchs (1954) and Williams and Mansour (2002). It has shown persistent relationship with their results. This numerical analysis developed by boundary element method will be applied for various offshore structures to be constructed in coastal zones in the future.
