Skin Friction Measurements On A NACA 0012 Airfoil Using Hot-Films.

Experimental Results Of Mean Surface Skin Friction Using Hot-Films On A NACA 0012 Airfoil At Low Speeds Are Presented. The Gauges Were Calibrated (In-Situ)In The Turbulent Boundary Layer Growing On The Airfoil Surface. Boundary Layer Computations Employing The Well Known Lag-Entrainment Method Of Green Have Been Used For Calibrating These Gauges
