HYDRODYNAMIC COEFFICIENTS OF A WAVE ENERGY DEVICE CONSISTING OF A BUOY AND A SUBMERGED PLATE

Hydrodynamic coefficients of a wave energy device consisting of a buoy connected to a submerged plate, are presented. Both the buoy and the plate are idealised as vertical cylinders. For this two-body system the case with the buoy oscillating vertically and the case with the submerged plate oscillating vertically are treated. The coefficients are solved by the method of matched eigenfunction expansions. Numerical results showing the plate's influence on the hydrodynamic coefficients of the buoy and vice versa are presented.
