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.

Measurements of Time-Space Distribution of Convective Heat Transfer to Air Using a Thin Conductive Film

TL;DR: Nakamura et al. as mentioned in this paper measured the time-space characteristics of heat transfer to air using a thin conductive film and a high-speed infrared thermograph, and the results showed that the timespace behavior of the heat transfer was clearly revealed by the streaks formed in the near-wall region of the turbulent boundary layer.

On the behaviour of organised disturbances in a turbulent boundary-layer

TL;DR: In this paper, the role of hydrodynamic stability theory in understanding wall-bounded turbulent flows was discussed, and numerical results showed that the linear instability modes are damped, a result also confirmed by our earlier work for the boundary layer flow case.

Instationnarités dans une bulle de décollement turbulente : étude expérimentale

TL;DR: In this article, a bi-modale dynamique of the TSB is defined, which is defined as the dynamique d'un ecoulement turbulent massivement decolle ou bulle de decollement turbulente (TSB).

Experimental review of devices to artificially thicken wind tunnel boundary layers

TL;DR: In this article, three devices that artificially increase the thickness of the boundary layer in a wind tunnel working section have been tested, including a serrated fence to disturb the flow, and the use of various secondary jet arrays injected into the boundary layers through the bounding surface.

The effects of concave curvature on turbulent boundary layer structure

TL;DR: In this paper, a flat plate turbulent boundary layer was grown on one wall of a straight, large water channel and then passed over a concave wall, and the flow was visualized in two ways: injecting dyes into the sublayers and generating hydrogen bubbles on fine wires placed in the flow.

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.
