Wind Tunnel Tests of a Thick Wind Turbine Airfoil
Wind Energy, Volume 27, Issue 10, Page 994-1010, October 2024.ABSTRACT This article reports about a wind‐tunnel experiment carried out in the ONERA F2 low‐speed wind tunnel on a model of the DU 97‐W‐300Mod airfoil designed for wind turbine application. The wind tunnel, the airfoil model, and experimental techniques used are presented, with special emphasis on the data processing and corrections required to derive
