Research on the Blade Motion of a Bidirectional Energy-Generating Turbine under Integrated Wave and Tidal Current Action

open access: yesJournal of Marine Science and Engineering, 2021
An integrated wave-tidal current power turbine is affected by both wave and tidal current forces, and its energy efficiency is closely related to the velocity and direction of the two forces.

Hydrodynamic loadings on a horizontal axis tidal turbine prototype [PDF]

open access: yes, 2017
Until recently tidal stream turbine design has been carried out mainly by experimental prototype testing aiming at maximum turbine efficiency. The harsh and highly turbulent environments in which tidal stream turbines operate in poses a design challenge ...

Study on Impact of Turbine Location on Hydrodynamics in Tidal Farm

open access: yesDiscrete Dynamics in Nature and Society, 2019
This work aims at investigating the impact of different tidal turbine locations on hydrodynamics in near-field and far-field flow; thus, three- and two-dimensional (3- & 2-D) models were exploited in combination and applied in a case study of Putuo-Hulu ...

Analysis of the kinetic energy recovery behind a tidal stream turbine for various submergence levels

open access: yesInternational 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 ...

Wake of a Ducted Vertical Axis Tidal Turbine in Turbulent Flows, LBM Actuator-Line Approach

open access: yesEnergies, 2019
Vertical axis tidal turbines are devices that extract the kinetic energy from tidal currents. Tidal currents can be highly turbulent. Since ambient turbulence affects the turbine hydrodynamic, it is critical to understand its influence in order to ...

Hydrodynamic Analysis of Tidal Current Turbine under Water-Sediment Conditions

open access: yesJournal 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.
