TLDR
There have been well over two hundred experimental studies published on the turbulent wall jet as mentioned in this paper, of which about one half have been prompted by heat transfer considerations and in most of these cases the flow field has been insufficiently well documented to merit close attention for the present purpose.About:

Journal ArticleDOI
On the applicability of various scaling laws to the turbulent wall jet
TL;DR: In this article, the authors measured the spatial distribution of the mean velocity in a two-dimensional turbulent wall jet and determined that the bulk of the flow is self-similar and it depends on the momentum flux at the nozzle and on the viscosity and density of the fluid.
Journal ArticleDOI
An experimental study of a two-dimensional plane turbulent wall jet
TL;DR: In this paper, laser-Doppler measurements were conducted in a plane turbulent wall jet at a Reynolds number based on inlet velocity, Re0, of 9600, and the initial development as well as the fully developed flow was studied.
Journal ArticleDOI
The mathematical modelling of turbulent flows
TL;DR: A review of the problems and successes of computing turbulent flow can be found in this article, with a summary of the advantages and disadvantages of the various turbulence models, in an attempt to assist the potential user in choosing the most suitable model for his particular problem.

A similarity theory for the turbulent plane wall jet without external stream
William K. George,Hans Abrahamsson,J. A. N. Eriksson,Rolf Karlsson,Lennart Löfdahl,Martin Wosnik +5 more
TL;DR: In this paper, a new theory for the turbulent plane wall jet without external stream is proposed based on a similarity analysis of the governing equations, which is shown to be in excellent agreement with the experimental data which show that source conditions may determine uniquely the asymptotic state achieved.

Wall pressure and shear stress measurements beneath an impinging jet
C.V. Tu,David Wood +1 more
TL;DR: In this paper, the authors measured wall pressure and surface shear stress under a plane, two-dimensional, turbulent jet impinging normally onto a flat surface and found that the wall pressure distributions are nearly Gaussian, independent of Reynolds number, and closely balance the momentum flux from the jet nozzle as H D varies.

Journal ArticleDOI
Calibration of the Preston tube and limitations on its use in pressure gradients
TL;DR: In this paper, it is shown that in sufficiently strong favorable and adverse pressure gradients the inner-law velocity distribution breaks down completely, and it is suggested that this breakdown is associated with reversion to laminar flow.

The two-dimensional turbulent wall-jet
W. H. Schwarz,W. P. Cosart +1 more
TL;DR: In this paper, the mean velocity distribution of the incompressible, turbulent, plane wall-jet has been examined in some detail with the aid of a hot-wire anemometer.

Report on the first European Mechanics Colloquium, on the Coanda effect
R. Wille,H. H. Fernholz +1 more
TL;DR: The first European research conference on boundary layers and jets on highly curved walls was held in Berlin on 5 and 6 April 1965 as discussed by the authors, with a focus on the Coanda effect.
Journal ArticleDOI
Measurements in a self-preserving plane wall jet in a positive pressure gradient
TL;DR: In this paper, the authors measured a wall jet in a self-preserving pressure gradient with a linearized hot-wire anemometer and measured the mean velocity, the turbulence stresses, triple and quadruple velocity correlations, intermittency and spectra of the longitudinal turbulence intensity.

Three-Dimensional Turbulent Wall Jets
Nallamuthu Rajaratnam,B. S. Pani +1 more
TL;DR: In this article, experiments on three-dimensional turbulent bluff wall jets originating from circular, elliptic, square, rectangular, and equilateral triangular nozzles have shown that the distribution of the axial velocity in the central as well as transverse planes is similar.
