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.

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.

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

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)

Energies, 2013 Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy.

Journal of Marine Science and Engineering, 2019 Estimating the energy potential of tidal stream site is a key feature for tidal energy system deployment. This paper aims to compare two methods of prediction of tidal current velocities. The first one is based on the use of a fully three-dimensional (3D)

Analysis of the kinetic energy recovery behind a tidal stream turbine for various submergence levels
International Marine Energy Journal, 2022 Tidal turbines are commonly deployed at sea sites with water depths of up to 50 m to ease their deployment and quick maintenance operations. In these relatively shallow water depth conditions, the vertical expansion of tidal stream turbine wakes is ...
