Abstract
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.

Turbulent Boundary-Layer Heat Transfer from Rapidly Accelerating Flow of Rocket Combustion Gases and of Heated Air

TL;DR: In this paper, the turbulent boundary-layer heat transfer from rapidly accelerating flow of rocket combustion cases and of heated air is discussed, and it is shown how far existing methods of analysis may be in error under the limited conditions thus far investigated, and some basis for corrections to these analyses that will permit an acceptable prediction of the heat transfer for most requirements.

Study of turbulent structure with hot wires smaller than the viscous length

TL;DR: In this article, the small-scale structure of the streamwise velocity fluctuations in the wall region of a turbulent boundary layer is examined in a new wind-tunnel facility using hot-wires smaller than any previously constructed (typical dimensions: l = 25 μm, d = 0.5 μm).

Effect of Reynolds number on a slightly heated turbulent boundary layer

TL;DR: In a slightly heated turbulent boundary layer, this paper showed that the extent of these regions, as a proportion of the boundary layer thickness, is approximately constant, independent of the momentum thickness Reynolds number when R m ⪞ 3100.

The Askervein hill project: A finite control volume prediction of three-dimensional flows over the hill

TL;DR: In this paper, a three-dimensional nonlinear numerical model was applied to predict the flow over an isolated hill, Askervein, in order to predict wind speeds approaching the hill from 210° and 180° clockwise from north.

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

John Laufer
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

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.
