Wake Expansion and the Finite Blade Functions for Horizontal-Axis Wind Turbines
This paper considers the effect of wake expansion on the finite blade functions in blade element/momentum theory for horizontal-axis wind turbines. For any velocity component, the function is the ratio of the streamtube average to that at the blade ...

Towards smart blades for vertical axis wind turbines: different airfoil shapes and tip speed ratios
Abstract. Future wind turbines will benefit from state-of-the-art technologies that allow them to not only operate efficiently in any environmental condition but also maximise the power output and cut the cost of energy production. Smart technology, based on morphing blades, is one of the promising tools that could make this possible. The present study
