DU00-W-212 airfoil polars, mimicked DanAero inflow
Description
Averaged lift and drag coeffficients of a DU00-W-212 profile in turbulent inflow generated with an active grid at Reynolds numbers 500,000 and 900,000. The inflow pattern was mimicked from measurements a the blade with a 5-hole pressure probe performed in teh DanAero project.
Data is obtained with a three-component load cell and via integration of 48 scanned pressure tabs along the chord.
Standard wind tunnel corrections according to Allen & Vincenti are applied.
Data sets 203, 204, 210, 211: flow tripped on the surface at 1.5% chord on upper airfoil side, 10% chord on lower airfoil side
Data sets 203, 211, 225, 230: measured starting at positive angles of attack (AOA) to negative AOAs
Data sets 204, 210, 224, 239: measured starting at negative angles of attack (AOA) to positive AOAs
The experiment was performed within in the EU-funded project AVATAR (www.eera-avatar.eu).
