| Abstract: | Experiments have been conducted to measure in incompressible flow the local surface-shear stress and the average skin-friction coefficient for a turbulent boundary layer on a smooth, flat plate having zero pressure gradient. The local surface-shear stress was measured by a floating-element skin-friction balance and also by a calibrated total head tube located on the surface of the test wall. The average skin-friction coefficient was obtained from boundary-layer velocity profiles. The boundary-layer profiles were also used to determine the location of the virtual origin of the turbulent boundary layer. Data were obtained for a range of Reynolds numbers from 1 million to about 45 million with an attendant change in Mach number from 0.11 to 0.32. |
