A numerical solution of the second-order wave-diffraction problem for a submerged cylinder of arbitrary shape

Abstract

The first- and second-order wave-diffraction problems are solved for a submerged cylinder of arbitrary shape by the integral-equation method based on Green's theorem. The integral equation is solved by an element method using cubic splines. The first- and second-order force components, transmission and reflection coefficients are presented for two fifferent contours. The results for the circular contour are compared with experimental results.
