This study is about the meandering phenomenon of a wind turbine wake. The atmospheric boundary layer is reproduced in a wind tunnel as well as wind turbines using porous discs. Hot wire anemometry is used to carry out time investigations through the study of space-time correlations. Particle Image Velocimetry is also used to observe the spatial development of the wake and especially the horizontal oscillations characterising the meandering.
