Experimental Techniques for Analyzing the Turbulent Boundary Layer
Abstract
In this report some of the methods for analyzing the turbulent boundary layer are applied to experimental data measured in full scale flight test. The values of turbulent surface shear coefficient, C sub f, were obtained using several experimental techniques and theoretical methods. The measured boundary layer growth was very much in excess of the growth predicted by Ross' treatment of the momentum equation. The values of turbulent shear measured by Clauser's method were in good agreement with values found by Preston's method. However, the Squire and Young formula used with experimentally determined values of momentum thickness and velocity yielded values of surface shear considerably higher than either of the experimental methods. The values of surface shear obtained from the von Karman momentum equation showed erratic scatter and, in general, increasing trends toward separation.
