An experimental study of entrainment and transport in the turbulent near wake of a circular cylinder

This paper describes an experimental investigation of transport processes in the near wake of a circular cylinder a t a Reynolds number of 140000. The flow in the first eight diameters of the wake was measured using X-array hot-wire probes mounted on a pair of whirling arms. This flying-hot-wire technique increases the relative velocity component along the probe axis and thus decreases the rela...

Statistical Description in the Turbulent Near Wake of a Rotating Circular Cylinder

Turbulence studies were made in the wake of a rotating circular cylinder in a uniform free stream. The interest was to examine the turbulence properties at the suppression of periodicity in vortex formation process. An experimental study of the turbulent near wake of a rotating circular cylinder was made at a Reynolds number of 9000 for velocity ratios, λ between 0 and 2.7. Hot-wire anemometry ...

Three-Dimensional Instabilities in the Wake of a Circular Cylinder

Mark Thompson Kerry Hourigan John Sheridan Department of Mechanical Engineering, Monash University, Clayton, Australia • The twoand three-dimensional wake structure behind a circular cylinder has been computed using a high-order spectral element technique. For the two-dimensional computations the predictions are compared with accurate experimental results and agree to within experimental uncert...

The shear-layer instability of a circular cylinder wake

A reinterpretation is made of previously published data concerning the frequency of the instability waves in the separated shear layer from a circular cylinder for Reynolds numbers in the range 103–105. An accurate fit to the observed variation can be achieved using a piecewise fit based on theoretical and empirical arguments. A logical conclusion is that the ratio of the frequency of the insta...

3D-simulation of the turbulent wake behind a wind turbine

The paper relates to the simulation of the airflow around a wind turbine (WT) of the type ENERCON E66 with emphasis on the turbulent wake. The simulations were undertaken with the Computational Fluid Dynamics (CFD) software ANSYS FLUENT 6.3 using the LES technique for turbulence modeling. It is the aim of the work to capture the full threedimensional turbulent flow behind a WT in a sufficient s...
