Measurements of the Reynolds stress tensor in a three-dimensional turbulent boundary layer under infinite swept wing conditions

On a wind tunnel model measurements have been made of the six components of the Reynolds stress tensor in a three-dimensional incompressible turbulent boundary layer under infinite swept wing conditions in an adverse pressure gradient, with a three-dimensional separation near the trailing edge. These measurements complement the mean velocity...

A model for calculation of the properties of a jet in a cross flow

A semi empirical model is derived for the calculation of the properties of a jet exhausting into a cross flow, at an arbitrary initial angle. The main empirical input is the velocity decay along the jet axis, derived from available measurements. The model is a generalization of an earlier model for a jet exhausting perpendicularly into a cross...

Computational Modeling of Turbulent Transport

A rational closure technique is presented for the first and second moment-equations in a stratified, contaminated turbulent flow, Following the application of high Reynolds/Peclet number approximations, remaining third moments are expanded about the isotropic, homogeneous state. The stratified, uncontaminated case reduces to seventeen equations...

The law of the wall in two- and three- dimensional turbulent boundary layers

The law of the wall has been extended to three-dimensional flows, The effects of both the pressure gradient and the inertial forces have been considered. The deduced wall law is valid when the deviations from the simple two-dimensional law of the wall are small. Agreement with measurements is found within the possible experimental error.

Memory Effect in a Turbulent Boundary-Layer Flow Due to a Relatively Strong Axial Variation of the Mean-Velocity Gradient

Measurements have been made of the distributions of mean velocity, turbulence intensities and turbulence shear-stress in a turbulent boundary-layer downstream of a hemi-spherical cap attached onto the plane rigid wall. The eddy-viscosity, when computed in the classical way according to Boussinesq's concept from the lateral gradient of the mean...

Measurements in a three-dimensional incompressible turbulent boundary layer in an adverse pressure gradient under infinite swept wing conditions

On a wind tunnel model, especially designed to check calculation methods, measurements were made of a three-dimensional turbulent boundary layer under infinite swept wing conditions in an adverse pressure gradient, with a three-dimensional separation near the trailing edge. Accurate measurements of the external flow field, the mean velocity...

Measurement of turbulent fluctuations in a closed conduit, detailed data of the spectrum of the measured turbulence.

Measurement of the Reynolds Stresses in a Circular Pipe as a Means of Testing a DISA Constant-Temperature Hot-Wire Anemometer

Measurements of the turbulent stresses in fully-developed pipe flow have been made as an overall test of the DISA constant-temperature hot-wire anemometer. The measurements were made with single slanting wires and a normal wire. The shearing stress was measured at two Reynolds numbers and compared with values computed from the pressure drop down...

Enkele aspekten van het instibiliteitsverschijnsel bij permanent eenparige stromin en de daarmee verband houdende vorming van rolgolven

Het doel van dit onderzoek is de bestudering van enkele eigenschappen van een stromingswijze, welke gewoonlijk wordt aangeduid met de naam "rolgolven". De rolgolven behoren tot de grote familie van de z.g. zwaartekrachtgolven; alhoewel binnen deze groep de rolgolven geen plaats van overwegende betekenis innemen, zijn zij toch indirect belangrijk...
