Experimental studies of the mean velocity profiles and of the wall pressure fluctuations within the axially symmetric turbulent boundary layer on cylinders of various diameters have been made. The measurements include the mean velocity and shear stress on cylinders with diameters ranging from 0.02 to 2.0 inches. A very small hot wire probe and simple anemometer circuit was developed and acoustically calibrated. The hot-wire measurements were used to determine the wall shear stress on the smallest diameter cylinders. A Preston tube was used to measure the shear stress on the larger cylinders.
