Instabilities in the Wake of a Circular Cylinder with Near-wake Wire Disturbances
The secondary instabilities in the wake of a circular cylinder with near-wake wire disturbances are investigated by using threedimensional (3D) direct numerical simulations (DNS). For one wire placed asymmetrical about the wake centreline and two wires placed symmetrical about the wake centreline, the secondary instabilities are found to be Mode C and Mode A, respectively. The existence of the ...
متن کاملDynamics of a tilted cylinder wake in a stratified fluid
Despite the large amount of research devoted to bluff body wakes [1], very few studies have focused on stratified wakes despite their obvious applications to geophysical flows. Moreover, most of these studies have studied the turbulent regime in the wake of a sphere or an ellipsoid [2,3], due to its naval applications for submarine wakes. These bluff bodies have a finite height, which leads to ...
متن کاملZoology of Unstable Modes in a Stratified Cylinder Wake
This paper delineates experimental and numerical results concerning the effect of the stratification and the tilt on the 3D instabilities of a cylinder wake led at moderate Reynolds numbers from the 2D von Karman vortex street. For a vertical cylinder, shadowgraph visualisations put forward an unstable mode similar to the mode A well known in homogeneous fluids. When the cylinder is tilted a ne...
متن کاملAn 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...
متن کاملShear Layer Vortices and Longitudinal Vortices in the Near Wake of a Circular Cylinder
J. Soria Department of Mechanical Engineering, Monash University, Clayton, Australia • Results are presented on (1) the shear layer vortices developing in the free shear layers located between the separation point and the first shed Strouhal vortex of a circular cylinder and (2) the longitudinal vortices developing in the braid region of the Strouhal vortices in the wake. Evidence based on flow...
