Abstract

This paper presents an experimental and numerical study of the two-dimensional wave diffraction by a fixed horizontal-axis submerged circular cylinder. The objective of the paper is to report and validate the results from the fully non-linear two-dimensional boundary-element method code CANAL and to assess the capability of the physical wave flume and the measurement methodology to study this type of problem. Two test cases are presented, both in deep-water conditions. The cylinder axis submergence is 1.5r (r being the cylinder radius) for the first case, and 3r for the second case, the later corresponding to the experimental study presented in the paper. A discretization convergence evaluation is also presented for the second case. The good agreement between the numerical and the experimental results proves that this numerical model is capable to simulate accurately this type of problems.
