Examining the relationship between wind turbine blade performance and tip vortex behaviour in the wake
Whale, J. (1997) Examining the relationship between wind turbine blade performance and tip vortex behaviour in the wake. In: Proceedings of the 19th British Wind Energy Conference, 16 - 18 July, Edinburgh, Scotland
This paper details the results of laboratory tests on a model wind turbine rotor at the University of Edinburgh and examines tip vortex behaviour which questions the assumptions of current rotor performance prediction codes. Results are compared with wind-tunnel data from the Technical University of Delft and simulations from a vortex wake code developed at the University of Stuttgart. A Biot-Savart calculation is undertaken to provide insight into how the observed tip vortex effects may affect the calculation of performance of a wind turbine rotor.
