An experimental investigation of a three-dimensional turbulent boundary layer
Abstract
Measurements of the mean velocities and Reynolds stress components have been made in a three-dimensional turbulent boundary layer generated by the zero longitudinal pressure gradient flow over a flat plate with a yawed leading edge. The primary instrument was a three-wire hot-wire anemometer probe connected to a specially designed analog computer. The measurements are shown to be self-consistent and indicate that the direction of the turbulent shear stress vector is not necessarily in the direction of the mean velocity gradient vector as implied by the eddy viscosity hypothesis.
