Abstract [en]

In this article we present a computational framework for simulation ofturbulent flow in marine based renewable energy applications. Inparticular, we focus on floating structures and rotatingturbines. This work is an extension to multiphase turbulent flow, ofour existing framework of residual based turbulence modeling forsingle phase turbulent incompressible flow. We illustrate theframework in four examples: a regular wave test where we compareagainst an exact solution, the standard MARIN wave impact benchmarkwith experimental validation data, a vertical axis turbine withcomplex geometry from an existing turbine, and finally a prototypesimulation of decay test in a coupled moving boundary rigid-body andtwo-phase fluid simulation.
