The Turbulent Boundary Layer on a Porous Plate an Experimental Study of the Fluid Mechanics for Adverse Free Stream Pressure Gradients

摘要

An experimental investigation of transpired turbulent boundary layers in zero and adverse pressure gradients has been carried out. Profiles of: (1) the mean velocity, (2) the three intensities of the turbulent fluctuations, and (3) the Reynolds stress were obtained by hot-wire anemometry. The friction coefficients were measured by using an integrated form of the boundary layer equation to extrapolate the measured shear stress profiles to the wall. (Author)
