Spanwise flow corrections for tidal turbines

International Marine Energy Journal, 2018
Actuator line computations of two different tidal turbine rotor designs are presented over a range of tip speed ratios. To account for the reduction in blade loading on the outboard sections of these rotor designs, a spanwise flow correction is applied ...

Towards a Generalized Tidal Turbine Wake Analytical Model for Turbine Placement in Array Accounting for Added Turbulence

Energies
This study seeks to establish a comprehensive model for estimating both the velocity deficit and turbulence intensity within a tidal turbine farm across various layout configurations.

Design of a Horizontal Axis Tidal Turbine for Less Energetic Current Velocity Profiles

Journal of Marine Science and Engineering, 2019
Existing installations of tidal-stream turbines are undertaken in energetic sites with flow speeds greater than 2 m/s. Sites with lower velocities will produce far less power and may not be as economically viable when using “conventional” ...

Verification and validation of blade-resolved viscous-flow tidal turbine simulations

International Marine Energy Journal
Tidal turbines are a renewable energy source on the rise. The exceptional predictability of tidal currents contributes to a high reliability of this technology, which represents a key advantage in the endeavor to become a major contributor to the energy

The Potential of Tidal Energy Production in a Narrow Channel: The Gulf of Morbihan

Journal of Marine Science and Engineering
The tidal currents of the Gulf of Morbihan reach up to 3.5 m/s within a narrow (200 m large) channel connecting the sea to the inner part of the gulf. In this study, a Telemac2D model validated with a large dataset of field measurements is used to assess

Orca hydrofoil shape optimization using Bezier curve and artificial neural network – multiple objective genetic algorithm for low flow velocity

Journal of King Saud University: Engineering Sciences
Tidal energy is a clean and predictable power source commonly harnessed using horizontal-axis tidal turbines. The power generation process of these turbines is influenced by various elements, including the hydrofoil performance metrics such as the lift ...
