Abstract

A numerical wave channel for the simulation of realistic offshore conditions based on the solution of the unsteady Reynolds-averaged Navier-Stokes equations is presented. The methodology combines a non-linear wave model with a Volume of Fluid calculation to generate an unsteady sea state. The aim is to assist the design process of offshore structures, with particular focus on tidal stream generators. A simulation strategy that focuses on capturing wave-current interaction is introduced and is validated with respect to fluid particle kinematics. Finally, a case study is presented that evaluates the flow field of a nonlinear wave simulated in combination with a non-uniform current.
