The results of an experimental investigation of a turbulent boundary layer with zero pressure gradient are presented. Measurements with the hot-wire anemometer were made of turbulent energy and turbulent shear stress, probability density and flattening factor of u-fluctuation (fluctuation in x-direction), spectra of turbulent energy and shear stress, and turbulent dissipation. The importance of the region near the wall and the inadequacy of the concept of local isotropy are demonstrated. Attention is given to the energy balance and the intermittent character of the outer region of the boundary layer. Also several interesting features of the spectral distribution of the turbulent motions are discussed.read more

Flowfield measurements in a separated and reattached flat plate turbulent boundary layer
TL;DR: In this paper, the separation and reattachment of a large-scale, two-dimensional turbulent boundary layer at low subsonic speed on a flat plate was studied experimentally using a combination of laser velocimetry, hot-wire anemometry, pneumatic probing techniques, and flow visualization.

Plume dispersion from ground level sources in simulated atmospheric boundary layers
TL;DR: In this article, measurements of plume dispersion in urban and rural simulated boundary layers are compared with full-scale data and theoretical treatments of the plume behavior, and the results of the comparisons are then used to demonstrate that the observed plume behaviour observed in the wind tunnel was a reasonable simulation of the Pasquill class D-C atmospheric behaviour.

Estimation of turbulent energy dissipation in the boundary layer using Smoke Image Velocimetry
TL;DR: In this article, the authors used smoke image velocimetry technique based on digital processing of smoke visualization of flow and adapted to relatively large smoke displacement between two consecutive video frames.

The Local Structure of Turbulence in Incompressible Viscous Fluid for Very Large Reynolds' Numbers
TL;DR: In this article, the authors consider the problem of finding the components of the velocity at every point of a point with rectangular cartesian coordinates x 1, x 2, x 3, x 4, x 5, x 6, x 7, x 8.
The Structure of Turbulence in Fully Developed Pipe Flow
TL;DR: In this paper, a hot-wire anemometer was used to measure the turbulent flow in a 10-inch pipe at speeds of approximately 10 and 100 feet per second, and the results include relevant mean and statistical quantities, such as Reynolds stresses, triple correlations, turbulent dissipation, and energy spectra.

Investigation of turbulent flow in a two-dimensional channel
TL;DR: A detailed exploration of the field of mean and fluctuating quantities in a two-dimensional turbulent channel flow is presented in this article, where mean speed and axial-fluctuation measurements were made well within the laminar sublayer.
Some Features of Artificially Thickened Fully Developed Turbulent Boundary Layers with Zero Pressure Gradient
P S Klebanoff,Z W Diehl +1 more
TL;DR: In this article, the feasibility of artificially thickening a turbulent boundary layer on a flat plate was investigated and it was shown that it is possible to do substantial thickening and obtain a fully developed turbulent boundary layers, which is free from any distortions introduced by the thickening process.
