Abstract

Local and intermittent changes in wind speed may induce a higher angle of attack of a wind turbine rotor blade leading to flow separation. The effect of flow separation to the surface pressure fluctuation (SPF) and trailing-edge noise (TEN) was measured in the Acoustic Wind-tunnel Braunschweig using a directional microphone and miniature surface pressure sensors. The measurements were conducted using a DU96-W-180 rotor blade profile at pre-stall angles of attack [69]. Because of the limitation of the directional microphone, the maximum sound pressure level at a frequency lower than 1 kHz was not attainable. Therefore, a predictive model of the TEN using the surface pressure fluctuations is needed.
