SECOND-ORDER WAVE INTERACTION WITH ARRAYS OF VERTICAL CYLINDERS OF ARBITRARY CROSS SECTION

Keisuke Murakami, Akinori Yoshida

Abstract


This paper proposes an approximate calculation method for the secondorder wave interactions with arrays of vertical cylinders of arbitrary cross section. In mathematical formulations, the first- and the second-order boundary value problems are derived by perturbation method, and Green's Identity Formula is used to express the distribution of the velocity potentials on horizontal plane. Second-order water surface elevations near the cylinders and wave forces acting on the cylinders are computed, and the results are verified by comparing with wave tank experiments in the valid range of the Stokes second-order wave theory.
