Publikováno v: Meyer Forsting, A R, Troldborg, N, Murcia Leon, J P, Sathe, A, Angelou, N & Vignaroli, A 2017, ' Validation of a CFD model with a synchronized triple-lidar system in the wind turbine induction zone ', Wind Energy, vol. 20, pp. 1481-1498 . https://doi.org/10.1002/we.2103

A novel validation methodology allows verifying a CFD model over the entire wind turbine induction zone using measurements from three synchronized lidars. The validation procedure relies on spatially discretizing the probability density function of t

Modelling lidar volume-averaging and its significance to wind turbine wake measurements:Paper

Autor: Meyer Forsting, Alexander Raul, Troldborg, Niels, Borraccino, Antoine

Publikováno v: Meyer Forsting, A R, Troldborg, N & Borraccino, A 2017, Modelling lidar volume-averaging and its significance to wind turbine wake measurements : Paper . in Wake Conference 2017 . vol. 854, 012014, Journal of Physics: Conference Series, Wake Conference 2017, Visby, Sweden, 30/05/2017 . https://doi.org/10.1088/1742-6596/854/1/012014

Lidar velocity measurements need to be interpreted differently than conventional in-situ readings. A commonly ignored factor is “volume-averaging”, which refers to lidars not sampling in a single, distinct point but along its entire beam length.

Traditionally met masts are used for power and load verifications. They are normally placed 2-4 rotor diameters ahead of the turbine. However in complex terrain this can lead to complex analysis of the effect of the terrain on the flow field. A nacel
