Optimization of a Grid-Connected Microgrid Using Tidal and Wind Energy in Cook Strait
The Cook Strait in New Zealand is an ideal location for wind and tidal renewable sources of energy due to its strong winds and tidal currents. The integration of both technologies can help to avoid the detrimental effects of fossil fuels and to reduce ...

Instabilities in tidal turbine wakes [PDF]
We report on the observation of vortex instabilities in the wake of a tidal turbine undergoing harmonic unsteady axial inflow (e.g. due to surface waves). The work was carried out using unsteady RANS (URANS) modelling using the open-source CFD software OpenFOAM, using the `pimpleDyMFoam' solver.

Influence of inlet line shape on hydrodynamic performance of tidal energy diffuser
The installation of diffuser is an important way to improve the efficiency of tidal turbines, which is promising for engineering practice. In this paper, the open source code OpenFOAM is used as the platform.

Study of a Bi-Vertical Axis Turbines Farm Using the Actuator Cylinder Method
Vertical axis turbines, which extract kinetic energy from currents, can produce electricity independently from a current’s direction. Hence, this type of turbines raises interest for harvesting energy from tidal currents, where flow changes direction ...

Blockage Corrections for Tidal Turbines—Application to an Array of Turbines in the Alderney Race
Tidal turbines are located in shallow water depths in comparison to their dimensions (15 m-diameter turbines in 40 m depths, typically). Constrained vertically by the water depth and laterally by neighbouring turbines, the flow within a tidal farm is ...
