Vortex-Breakdown Efficiency of Planar Regular Grid Structures—Towards the Development of Design Guidelines

Fluids
The work presented here aims to provide design guidelines to create vortex-damping structures. A design of experiment was developed to investigate the individual and combined effects of the geometrical properties of planar regular grid structures, i.e ...

On the phenomenon of vortex street breakdown

, 1971
A von Kármán vortex street generated in the usual way was subjected to a deceleration, thereby changing the ratio of longitudinal to lateral spacing between the vortices.

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 ...

Evolution of an Atmospheric Kármán Vortex Street From High‐Resolution Satellite Winds: Guadalupe Island Case Study

, 2020
Vortex streets formed in the stratocumuluscapped wake of mountainous islands are the atmospheric analogues of the classic Krmn vortex street observed in laboratory ows past bluff bodies.

On the origin of the secondary vortex street

, 2012
The origin of the secondary vortex street, observed in the far wake in the flow past a circular cylinder, is investigated. The Reynolds number, based on the diameter of the cylinder, is 150. The von Kármán vortex street, which originates in the near wake,

Three-dimensional secondary instability of a spatially developing von Kármán vortex street in a far wake

, 2010
This paper presents studies of a three-dimensional secondary instability of a spatially developing von Kármán vortex street. It develops owing to the nonlinear interaction between a two-dimensional mean far-wake flow and its most unstable disturbances ...
