Numerical Simulation of Regular Waves onto a Vertical Circular Cylinder

Wave run-up phenomenon is of great significance during the design of a fixed or floating structure. In this work, the wave run-up on a truncated surface-piercing circular cylinder is investigated using a numerical wave tank. The numerical simulations are carried out by the in-house CFD solver naoe-FOAM-SJTU which is developed on the open source platform OpenFOAM. The volume of fluid (VOF) method is applied to capture the free surface. The surface elevation around the cylinder is probed by a series of wave gauges and analyzed using the Fourier analysis. The response amplitude operates (RAOs) of surface elevation are presented and compared with experimental data. Reasonable agreement shows the present solver is capable to investigate the wave run-up on a cylinder. The local surface elevation around the cylinder, the wave force and the scattered wave field around the cylinder is also investigated in detail.
