Abstract
A three-dimensional numerical study has been undertaken to investigate the interactions of a steep focused wave and a vertical circular cylinder. The large-eddy simulation approach has been adopted in this study, where the model is based on the filtered Navier–Stokes equations, with the dynamic Smagorinsky subgrid model being used for the unresolved scales of turbulence. The governing equations have been discretised using the finite volume method, with the air–water interface being captured using a volume-of-fluid method and the Cartesian cut-cell method being implemented to deal with the cylinder and moving wavemaker in the Cartesian grid. Numerical results are presented and compared with the available experimental measurements in terms of the wave elevations and pressure on the cylinder. Detailed free surface profiles during wave impact are shown and discussed.
