WALL SHEAR STRESS AND MEAN-VELOCITY MEASUREMENTS IN A THREE-DIMENSIONAL TURBULENT BOUNDARY LAYER

A three-dimensional smooth wall turbulent boundary layer with a moderate adverse pressure gradient was produced on the floor of a wind tunnel. The boundary layer velocity profile was measured at two positions, using a three-tube pressure probe. The streamwise, skin-friction coefficient was calculated with the skin-friction laws of Granville and Ludwieg and Tillmann using experimentally obtained boundary layer parameters. The results were compared with skin-friction coefficients obtained by using Preston tubes. (Modified author abstract)
