The impact of turbulence and turbine operating condition on the wakes of tidal turbines [PDF]
Renewable Energy, 2021 Before initiating a study on the interaction of multiple wakes, it is imperative that turbine wake hydrodynamics are studied in isolation. In this paper CFD computer simulations of downstream turbine wakes have been run using a scale-resolving hybrid turbulence model known as a detached eddy simulation.
