Near-wall similarity in two- and three-dimensional turbulent boundary layers
… from Preston tubes, direct wall shear using a two-dimensional (single line of action) floating element device, and direct wall shear measurements from an omnidirectional floating element capable of simultaneously determining magnitude and direction of a wall shear vector were completed over a …

A study of two- and three- dimensional turbulent boundary layer data sets using momentum integral techniques
An examination of selected two- and three-dimensional turbulent boundary layer data sets was made to determine the consistency of these data sets with their appropriate momentum integral equations. Several turbulent boundary layer experiments were reviewed to determined which of these provided …

A study of velocity profile models and wall shear stress for two and three-dimensional turbulent boundary layer flows
… more prominent velocity profile models for two and three-dimensional incompressible flows was presented, with emphasis placed on those that had previously shown their ability to correlate experimental data taken under various conditions. This review included velocity profile models that …

Design and application of a novel Laser-Doppler Velocimeter for turbulence structural measurements in turbulent boundary layers
… structural measurements in high Reynolds number two- and three-dimensional turbulent boundary layers. The new instrument combines, for the first time, new techniques allowing for the direct measurement of particle acceleration and sub-measurement-volume-scale position resolution so that …

Finite element solution of the Navier-Stokes equations for 3-D turbulent free shear flows
… to described the eddy viscosity distribution of two and three-dimensional turbulent free shear flows. The model is derived by integrating the parabolized transport equation for the turbulence kinetic energy over the cross section of the flow. The Prandtl-Kolmogrov hypothesis is used to obtain an …

Effect of wall motion on a two-dimensional turbulent boundary layer
Three-dimensional (3-D) turbulent flows are widely observed in many flow configurations. Flow over swept wings, through turbine passages, through curved ducts are a few examples of 3-D flows in practical applications. However, as compared to two-dimensional (2-D) turbulent flows, there are few …
