Abstract

Abstract

A system consisting of one floating rectangular cylinder on the free surface and one submerged rectangular cylinder has been applied to a wave energy conversion device in the water of a finite depth. The radiation problem for the wave energy device consisting of dual rectangular cylinders under plane incident wave altim is solved using an eigenfunction expansion method, a new analytical expression for the radiation velocity potential is obtained and then a wave excitation force is calculated by means of the theorem of Haskind that depends on the known incident wave potential and the radiation potential. To verify the correctness of the method, a numerical method is used to recompute the same example, and the obtained results are in good accordance with the analytical method, which shows that the present method is correct. Otherwise using the present analytical solution, the trends of hydrodynamic coefficients and wave force are analyzed under different conditions.
