Tidal current resource assessment [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007
This paper outlines present thinking on the determination of accessible tidal current resources within channels and other potentially exploitable locations. The fundamental principles behind tides and tidal currents are briefly discussed and the implications of temporal and spatial variations on the evaluation of the resources considered in the ...

Dynamics of a Tidal Current System in a Marginal Sea: A Case Study of the Yellow Sea, China

open access: yesFrontiers in Marine Science, 2020
Tidal currents belong to the main driving forces shaping the bathymetry of marginal seas. A globally unique radial sand ridge field exists in the South Yellow Sea off the central Jiangsu coast, China.

Comparative Investigations of Tidal Current Velocity Prediction Considering Effect of Multi-Layer Current Velocity

open access: yesEnergies, 2020
Accurate tidal current prediction plays a critical role with increasing utilization of tidal energy. The classical prediction approach of the tidal current velocity adopts the harmonic analysis (HA) method. The performance of the HA approach is not ideal

Unsteady wake modelling for tidal current turbines [PDF]

open access: yes, 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.
