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.

Engineering Computations, 1986
A mathematical model has been developed to study incompressible, isothermal, turbulent, confined, swirling flows. The model solves the conservation equations of mass, momentum, and two additional equations for the turbulent kinetic energy and the rate of dissipation of turbulent kinetic energy. The numerical predictions show a recirculation zone in the

Swirling flow between rotating plates
Archive for Rational Mechanics and Analysis, 1984The authors seek the solutions of the Navier Stokes equations in the form: \[ U_ x=xH'(z)-G(z)y+g(z);\quad \] \[ U_ y=yH'(z)+G(z)x- f(z);\quad U_ z=-H(z) \] and showed that H(z), G(z), g(z), f(z) satisfy a boundary value problem which constitutes the nonlinear von Kármán equations for axially symmetric swirling flow for functions H(z,\(\epsilon)\), G(z,

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.

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 ...

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 ...

Journal of Turbomachinery, 1988
The results of extensive laser measurements carried out in the blade passages of a newly designed backswept impeller are presented and discussed. Noticeable distortions of the throughflow patterns and a distinct swirling flow character were found inside the rotor.

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.

AbstractThe presence of vortex motion in a vertical cylinder in which water is passed upward can result in three types of velocity profiles: net upward motion at all points in the tube, an ascending outer annulus and a descending central core, and outer annulus and central core ascending and an intermediate annulus descending.All three types of ...
