Forces on a wave-energy module

Övrigt konferensbidrag, 1991

Mathematical models for the calculation of wave forces added mass and radiation damping of a wave energy module is developed in order to assess the energy take-out. The module consists of a buoy connected to a submerged plate by a so-called hose pump. In the present models the buoy and the submerged plate are idealized to two cylinders of equal radii. The presented method is founded on the method of matched eigenfunction expansion. Comparisons with other solutions are presented and the agreement is shown to be satisfactory. The developed models are computer efficient and will be used in an optimization procedure for a wave climate.
