Unsteady wake modelling for tidal current turbines [PDF]
IET Renewable Power Generation, 2011 The authors present a numerical model for three-dimensional unsteady wake calculations for tidal turbines. Since wakes are characterised by the shedding of a vortex sheet from the rotor blades, the model is based on the vorticity transport equations. A vortex sheet may be considered a jump contact discontinuity in tangential velocity with, in inviscid ...

The prediction of the hydrodynamic performance of tidal current turbines
IOP Conference Series: Materials Science and Engineering, 2013 Nowadays tidal current energy is considered to be one of the most promising alternative green energy resources and tidal current turbines are used for power generation. Prediction of the open water performance around tidal turbines is important for the reason that it can give some advice on installation and array of tidal current turbines.
