Effects of Particle Size on Dilute Particle Dispersion in a Karman Vortex Street Flow

, 2002
It is shown that in a Karman vortex street flow, particle size influences the dilute particle dispersion. Together with an increase of the particle size, there is an emergence of a period-doubling bifurcation to a chaotic orbit, as well as a decrease of ...

Secondary flows and heat transfer in shallow flow around a cylinder: LES, PIV

EPJ Web of Conferences, 2019
We report on Large-eddy simulations (LES) of flow around a short cylinder mounted in a narrow plane channel in a range of Reynolds numbers 1000, 2000, 3750 based on the bulk velocity of the flow and diameter of the cylinder supplemented with Particle ...

The vortex street as a statistical-mechanical phenomenon

, 1974
An explanation of the Karman vortex street is presented on the basis of the two-temperature canonical distribution for inviscid two-dimensional flows in Navier-Stokes fluids or guiding-center ...

Vortex-Induced Micro-Cantilever Vibrations with Small and Large Amplitudes in Rarefied Gas Flow

Applied Sciences
This study employs a fully coupled fluid–structure interaction (FSI) to investigate the vibrations of an elastic micro-cantilever induced by a rarefied gas flow.

Guide Vane Vibrations Caused by Wakes and Blower Noise—Part 1: The Vortex Degeneration in the Asymmetrical Wakes

, 1976
The symmetrical wakes beyond a guide vane cascade consisting of curved and flat plates with blunt trailing edges were investigated as far as the excited dynamic stresses in the blades and the vortex Strouhal number are concerned.

Simulation of Influence of Mechanical Elements on Karman Vortex Street Parameters

This work presents the results of numerical modeling of Karman vortex street generation performed with ANSYS/FLUENT package application. The influence of the mechanical elements located downstream of the bluff body on the vortex frequency has been found ...

Vortex dynamics in a viscous incompressible fluid

, 1994
An asymptotic theory of weakly interacting vortices is derived from the two dimensional incompressible Navier-Stokes equations. The scheme extends current perturbation theories by including arbitrary unperturbed core vorticity distributions and viscous ...

Quasi-periodic transverse plasma flow associated with an evolving MHD vortex street in the outer heliosphere

, 1993
We study a transverse (“meridional” in heliocentric coordinates) plasma flow induced by the evolution of a Karman vortex street using a Chebyshev-Fourier spectral algorithm to solve both the compressible Navier-Stokes and magnetohydrodynamic (MHD ...

Spanwise vortex dislocation in the wake of segmented blunt trailing edge

, 2012
Dislocation of the Karman vortex is forced in the near wake behind a two dimensional blunt trailing edge aerofoil to induce strong three dimensionality to weaken the Karman vortex and inhibit its periodic shedding by segmenting the trailing edge in a ...
