摘要

In this work, a three-dimensional (3D) numerical wave model based on a multi-block grid system was developed and applied to simulate the flow and pressure fields induced by water waves propagating over offshore structures. The unsteady, 3D Navier-Stokes equations were solved to simulate the viscous flow fields. The turbulence effects were modeled by large-eddy simulation (LES). The complex free surface configuration was captured by the level set method. The solid-fluid coupling method of Huang et al. [1] was employed to treat the interface between the fluid and solid boundary of irregular shape based on Cartesian grids. The proposed numerical model was applied to simulate the 3D lid-driven cavity flow and the wave fields induced by a solitary wave past a vertical circular cylinder. The good agreement between the numerical results and experimental data verifies the accuracy of the proposed 3D numerical wave model. Finally, the developed wave model was applied to simulate the wave propagation over an offshore mono-pile structure. The vortices on the lee-side of the pile could be observed in the numerical wave tank.
