Hydrodynamic Analysis of Tidal Current Turbine under Water-Sediment Conditions
Journal of Marine Science and Engineering, 2022 The rivers connecting oceans generally carry sediment due to water and soil losses in China. Additionally, the maximum sediment concentration is 300 g/L, which is much higher than that of other countries.

New Concept for Assessment of Tidal Current Energy in Jiangsu Coast, China
Advances in Mechanical Engineering, 2013 Tidal current energy has attracted more and more attentions of coastal engineers in recent years, mainly due to its advantages of low environmental impact, long-term predictability, and large energy potential.

Tidal Energy: The benthic effects of an operational tidal stream turbine
Marine Environmental Research, 2017 The effect of modified flow on epifaunal boulder reef communities adjacent to the SeaGen, the world's first grid-compliant tidal stream turbine, were assessed. The wake of the SeaGen was modelled and the outputs were used in conjunction with positional and substrate descriptor variables, to relate variation in epifaunal community structure to the ...

Numerical simulations of biofouling effects on the tidal turbine hydrodynamic
International Marine Energy Journal, 2018 Biofouling by benthic organisms must be considered for tidal turbine operation and maintenance because it modifies hydrodynamics (drag and resistance) and could be detrimental to the turbine performance.

Turbine sound may influence the metamorphosis behaviour of estuarine crab megalopae. [PDF]
PLoS ONE, 2012 It is now widely accepted that a shift towards renewable energy production is needed in order to avoid further anthropogenically induced climate change. The ocean provides a largely untapped source of renewable energy.

An optimal tuning strategy for tidal turbines [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 Tuning wind and tidal turbines is critical to maximizing their power output. Adopting a wind turbine tuning strategy of maximizing the output at any given time is shown to be an extremely poor strategy for large arrays of tidal turbines in channels. This ‘impatient-tuning strategy’ results in far lower power output, much higher structural loads and ...
