Optimization of hydrofoils for a bidirectional tidal stream turbine
Abstract Tidal stream turbines present an appealing approach for consistent renewable energy generation. Capitalizing on the periodic nature of tidal streams, these turbines can be designed to function bidirectionally, eliminating the need for a yaw control system. Although airfoils and hydrofoils in general have been extensively studied, there

Non-dimensional scaling of tidal stream turbines
Energy, 2012The impact of local depth-wise velocity profiles on tidal turbine performance is important. Although the use of standard power laws for predicting velocity profiles is common, these laws may underestimate the magnitude of the depth-wise velocity shear and power attenuation.

Reliability of tidal stream turbine blades
2011Tidal stream turbines are a new technology for extracting kinetic energy from tidal currents. A number of different concepts of such devices have been proposed up to now and the most popular of them is a horizontal-axis turbine with propeller-type blades.

The Physics of Fluids
The misalignment between flow and rotor can significantly alter the efficiency of the tidal stream turbine (TST), and therefore, it is vital to predict the flow in the tidal field and the performance of the TST under yaw-offset conditions.

Unsteady gust response of tidal stream turbines
2014 Oceans - St. John's, 2014This paper investigates the limitations of 2D linear unsteady aerofoil theory for modelling the unsteady gust response of tidal stream turbines. The work is motivated by the fact that accurate unsteady load prediction is required to determine turbine life.
