Swirl-Decay Mechanism Generating Counterflows and Cells in Vortex Motion

Journal of Engineering Thermophysics, 2021
This paper reviews counterflows, double counterflows, and circulation cells in vortex motion and argues that all these seemingly paradoxical phenomena can be caused by a common swirl-decay mechanism (SDM). It is shown that the SDM explains (a) the counterflow of water and oil in hydrocyclones, (b) the elongated counterflow of hot and cold air in vortex

Experimental Investigation of Swirling Vortex Motion in Jets

Journal of Applied Mechanics, 1967
Experiments have been carried out in a series of axisymmetric free turbulent jets with degrees of swirl covering the weak, moderate, and strong ranges, including the case of the onset of reversed flow in the central region of the jet. Measurements are reported of mean axial and swirl velocities, static pressure, and jet width at axial stations up to 15

Uninterrupted swirling motion facilitating ion transport in electrodialysis

Desalination, 2016
Abstract Performance analysis (ion transport per unit power consumption) of three different classes of flow promoters e.g. (i) twisted tape, (ii) twisted tape with cuts, and (iii) rod was tested in an electrodialysis setup with rectangular flow channel of fixed aspect ratio.

Motion of a swirled fluid in the core of a vertical, tornado-like vortex

Journal of Applied Mechanics and Technical Physics, 1995
The features of the motion of a swirled fluid in the core of a vertical tornado-like vortex are analyzed. A rigorous criterion for identifying qualitatively different behavior of the solutions as a function of the initial data are revealed. It is shown that analytical estimates agree in the order of magnitude with the observation results for laboratory

Analysis of Tumble and Swirl Motions in a Four-Valve SI Engine

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">Tumble and swirl motions in the cylinder of a four-valve SI engine with production type cylinder head were investigated using a cross-correlation digital Particle Image Velocimetry (PIV). Tumble motion was measured on the vertical symmetric plane of the combustion chamber.

Motion of Swirling Vortex Generated From Sharp Edge

Volume 2: Fora, Parts A and B, 2007
The siphon phenomenon is widely used for the transportation system of water and it is very economical and ecological because the natural energy of water is only used for the power source of the transportation system. The siphon phenomenon is continued while the water is supplied with from the entrance, and a large-scale separation flow forms near the ...

Observations of oscillatory motion in certain swirling flows

Journal of Fluid Mechanics, 1965
A descriptive experimental study was made in both air and water of the temporally periodic motion that occurs in the vortex whistle and cyclone separator. The motion can be described in terms of an oscillator that derives its energy from hydrodynamic instability of the steady swirling flow and whose frequency is determined by an angular velocity ...

A general formulation for the decay of swirling motion along a straight pipe

International Communications in Heat and Mass Transfer, 1994
Abstract This paper describes an analytical approach, based on the conservation of angular momentum flux, to predict the decay of swirling motion due to frictional effects along a straight duct. A combined forced vortex and shear-type velocity profiles were used and the analysis could be applicable to any types of swirling flow.
