Towards a Low-Cost Modelling System for Optimising the Layout of Tidal Turbine Arrays
Energies, 2015 In the long-term, tidal turbines will most likely be deployed in farms/arrays where energy extraction by one turbine may significantly affect the energy available to another turbine.

Tidal stream energy resource assessment in the Qiantang River Estuary, China
International Journal of Sustainable Energy, 2018 A tidal stream energy resource assessment can be achieved through direct measurements of tidal elevations or flow velocities, theoretical formulas, and numerical models. This paper first described the development of renewable energy in China.

Experimental Assessment of Flow, Performance, and Loads for Tidal Turbines in a Closely-Spaced Array
Energies, 2020 Tidal stream turbines are subject to complex flow conditions, particularly when installed in staggered array configurations where the downstream turbines are affected by the wake and/or bypass flow of upstream turbines.

Potential environmental impact of tidal energy extraction in the Pentland Firth at large spatial scales : results of a biogeochemical model [PDF]
, 2016 A model study was carried out of the potential large-scale (> 100 km) effects of marine renewable tidal energy generation in the Pentland Firth, using the 3-D hydrodynamics–biogeochemistry model GETM-ERSEM-BFM.

Turbulence and Wake Effects in Tidal Stream Turbine Arrays [PDF]
Volume 10: Ocean Renewable Energy, 2018 Electricity generation from tidal current can provide a reliable and predictable addition to a reduced carbon energy sector in the future. Following the deployment of the first multi-turbine array, significant cost reduction can be achieved by moving beyond demonstrator projects to large scale tidal turbine arrays.

Tidal-stream power assessment—A novel modelling approach
Energy Reports, 2020 An alternative approach for simulating turbine array energy capture, momentum sink-TOC, was developed to improve conventional methodologies for assessing tidal-stream energy resource.

Surface Characterisation of Kolk-Boils within Tidal Stream Environments Using UAV Imagery
Journal of Marine Science and Engineering, 2021 High-flow tidal stream environments, targeted for tidal turbine installations, exhibit turbulent features, at fine spatio-temporal scales (metres and seconds), created by site-specific topography and bathymetry. Bed-derived turbulent features (kolk-boils)

Tidal stream turbine power capping in a head-driven tidal channel [PDF]
Renewable Energy, 2019 Abstract An array of ten 1 MW turbines, with a one diameter inter-turbine spacing, is simulated in a hypothetical tidal channel using the depth-averaged flow solver TELEMAC-2D. It has been shown for idealised turbines that mean power extraction from tidal channels can be enhanced by tuning turbine resistance for a given channel.

Characterisation of underwater operational sound of a tidal stream turbine [PDF]
The Journal of the Acoustical Society of America, 2020 The underwater sound emitted during the operation of the Atlantis AR1500 turbine, a 1.5 MW three bladed horizontal axis tidal-stream turbine, was measured in the Pentland Firth, Scotland. Most sound was concentrated in the lower frequencies, ranging from 50 to 1000 Hz. Within 20 m of the turbine, third-octave band sound pressure levels were elevated by
