Comparison of unidirectional and bidirectional airfoils in a tidal stream turbine

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Tidal stream turbines offer an attractive method for stable renewable energy generation. Due to the periodicity of the tidal stream, a tidal stream turbine can be designed to operate in a bidirectional manner, thereby avoiding a yaw control system.

Multi-Point Shape Optimization of a Horizontal Axis Tidal Stream Turbine

Eng, 2021
A method was developed to perform shape optimization of a tidal stream turbine hydrofoil using a multi-objective genetic algorithm. A bezier curve parameterized the reference hydrofoil profile NACA 63815.

Advanced Functional Materials for Marine Energy Utilization

Interdisciplinary Materials, Volume 5, Issue 3, Page 317-356, May 2026.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

On tidal stream turbines placed off headlands [PDF]

Journal of Renewable and Sustainable Energy, 2015
Many candidate sites for tidal stream energy extraction can be classified as headland sites. Understanding the tidal resource of such sites is of fundamental importance to the industry. This paper examines an upper bound for the power that might be generated from an idealised headland. The dependence of this on length of turbine rows, number of turbine

Using Blade Element Momentum Theory to Predict the Effect of Wave-Current Interactions on the Performance of Tidal Stream Turbines

International Marine Energy Journal, 2021
The non-uniformity and dynamics of the environment tidal stream turbines need to operate within will significantly influence the durability and reliability of tidal energy systems.

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces
