Nonlinear Wave Forces on a Pair of Vertical Cylinders

Abstract

The present paper is concerned with development of a powerful scheme for calculating nonlinear wave forces on a pair of vertical cylinders with arbitrary cross sections. The Laguerre integration method is applied and its convergence is confirmed in the cases of a single vertical cylinder and a twin circular cylinder. Further, the present method is compared with the method given by Eatock-Taylor and Hung [9], and then the computational times and those properties for a numerical calculation are investigated. The numerical results for maximum wave forces on the vertical cylinders obtained by the present method are compared with the experimental results, so that the usefulness is clarified.
