Analysis of the high Reynolds number 2D tests on a wind turbine airfoil performed at two different wind tunnels
conference paper
2D wind tunnel tests at high Reynolds numbers have been done within the EU FP7 AVATAR project (AdVanced Aerodynamic Tools of lArge Rotors) on theDU00-W-212 airfoil and at two different test facilities: the DNW High Pressure WindTunnel in Gottingen (HDG) and the LM Wind Power in-house wind tunnel. Two conditions of Reynolds numbers have been performed in both tests: 3 and 6 million. The Mach number and turbulence intensity values are similar in both wind tunnels at the 3 million Reynolds number test, while they are significantly different at 6 million Reynolds number. The paper presents a comparison of the data obtained from the two wind tunnels, showing good repeatability at 3 million Reynolds number and differences at 6 million Reynolds number that are consistent with the different Mach number and turbulence intensity values.
