A coupled LES–aeroacoustic framework for predicting hydrodynamic noise from tidal-stream turbines

Applied Ocean Research
A high-fidelity numerical framework is developed to predict the hydrodynamic noise generated by tidal-stream turbines under realistic flow conditions.

Unsteady Loading on a Tidal Turbine Due to the Turbulent Wake of an Upstream Turbine Interacting with a Seabed Ridge

Energies
Tidal sites can present uneven seabed bathymetry features that induce favourable or adverse pressure gradients and are sources of turbulence, and so are likely to affect the operation, performance, and wake recovery dynamics of deployed tidal-stream ...

Numerical simulations of wake characteristics of a horizontal axis tidal stream turbine using actuator line model [PDF]

, 2017
The wake of a laboratory scale tidal stream turbine in a shallow water channel with a turbulent inflow is simulated using the hybrid LES/ALM technique, which combines large eddy simulation with the actuator line method. The turbulent inlet conditions are

Output characteristics of tidal current power stations

, 2004
With increasing targets being set for renewable-derived electricity generation, wind power is currently the preferred technology. It is widely accepted that due to the stochastic nature of wind, there is an upper limit to the capacity that can be ...

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume

, 2013
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...
