Computations of the Karman swirling flows are reported. They show four such flows and clearly indicate that an infinite sequence exists.

Flow Phenomena in Swirl Chambers
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 1997Results are presented from two different swirl chambers. One of the practical directions for this study is simulation of cooling passages located near the leading edges of turbine blades where screw-shaped, swirling flows are generated to enhance heat transfer.

Viscous flow in a swirl atomizer
Chemical Engineering Science, 1993Abstract In this paper a numerical analysis is carried out of the velocity field throughout a swirl spray nozzle and more specially at the orifice. After an examination of the parameters involved in the problem, it is found that the characteristics of the conical liquid sheet produced at the nozzle's orifice are mainly functions of the geometry of ...

Calculation of confined swirling flows
23rd Aerospace Sciences Meeting, 1985Swirling jets are an important constituent flow of many types of combustion equipment. Flame size, shape, stability and combustion intensity are all favorably influenced by swirling some portion of the incoming air with the fuel. Fluid dynamics computer codes are being developed for the mathematical simulation of flows in practical combustors.

Magnetohydrodynamics in turbulent swirling flow
1998We report an experimental study of the magnetic field fluctuations generated in a turbulent flow of liquid gallium, in the presence of an externally applied field. We consider the case of a weak‘seed’ field \({\vec B_0}\), so that the Lorentz forces do not modify the flow [1].

SWIRLING FLOWS OF VISCOELASTIC FLUIDS
Computers & Structures, 1988Few problems in Newtonian fluid mechanics can match the attention which has been given to the study of the flow of a Newtonian fluid between two parallel plates rotating about a common axis. Most of these analyses are based on the similarity transformation of Kármán to study axisymmetric solutions. Recently, \textit{S. V.

Experiments on swirling turbulent flows. Part 1. Similarity in swirling flows
Journal of Fluid Mechanics, 1973The effects of swirl on internal turbulent flows are studied by conducting experiments on turbulent pipe flow with variable initial swirl. This first part of the study is primarily concerned with similarity laws. The mean velocity profiles, both away from and close to the wall, are found to admit similarity representations at sufficiently large ...

Abstract The problem of the decay of a rotationally symmetric steady swirl superimposed on Poiseuille flow in a round pipe was investigated theoretically and experimentally. The object was to determine the degree to which the rate of decay of the swirl as predicted by a linearized theory agreed with measured rates of decay at flow ...

1. With an increase of the flow velocity v from 7.58 to 14.67 m/sec and change of k/kcr in the interval of the most erosion-active values from 0.75 to 0.39, Eph increases proportionally to v5, although Ef increases proportionally to v3. This indicates that in the presence of general erosion activity of the cavitation regime of the flow, a small ...
