“…Hsu and Wu (1999) again applied the boundary element method to the scattering of water wave by a submerged horizontal plate and a submerged permeable breakwater. Sannasiraj et al (1995) used the finite element technique to study the interaction of oblique waves with freely floating long structures. Then Sannasiraj et al (1998) adopted a two-dimensional finite element model to study the behavior of pontoon-type floating breakwaters in beam waves, and Sannasiraj et al (2000) again used the finite element method to study the diffraction-radiation of multiple floating structures in directional waves.…”

The system with one floating rectangular body on the free surface and one submerged rectangular body has been applied to a wave energy conversion device in water of finite depth. The radiation problem by this device on a plane incident wave is solved by the use of an eigenfunction expansion method, and a new analytical expression for the radiation velocity potential is obtained. The wave excitation force is calculated via the known incident wave potential and the radiation potential with a theorem of Haskind employed. To verify the correctness of this method, an example is computed respectively through the bound element method and analytical method. Results show that two numerical methods. are in good agreement, which shows that the present method is applicable. In addition, the trends of hydrodynamic coefficients and wave force are analyzed under different conditions by use of the present analytical method.

“…The method of solution combined both multiple and eigenfunction expansions and the effect of finite cylinder length and of the channel walls were discussed and the application is made to a line of Bristol Cylinder wave power devices. Sannasiraj et al (1996) have studied the diffraction/radiation boundary value problem arising from the interaction of oblique waves with freely floating structures using FEM. The effect of wave directionality and spreading index on motion responses is presented.…”

“…Hsu and Wu (1999) used again the boundary element method to the scattering of water wave by a submerged horizontal plate and a submerged permeable breakwater. Sannasiraj et al (1995) applied the finite element technique to study the interaction of oblique waves with freely floating long structures. The hydrodynamic behavior of two-dimensional horizontal floating structures under the action of the multi-directional waves has been investigated, and the motions and forces on a rectangular floating structure experiencing unidirectional and multi-directional wave fields were computed.…”
