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.

AIChE Journal, 1961
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 ...

Hydrotechnical Construction, 1993
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 ...

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].

Confined swirling flow predictions
21st Aerospace Sciences Meeting, 1983The validity of flowfield predictions resulting from the choice of inlet velocity profiles is assessed. Results demonstrate that realistic predictions are forthcoming only from the inclusion of realistic axial, radial and swirl velocity profiles as inlet conditions.

25th AIAA Aerospace Sciences Meeting, 1987
The physics of the flow interaction between swirl and secondary flow was studied in duct bends relevant to the design of advanced aircraft nozzle systems. Both laminar and turbulent subsonic flows were investigated in generic duct bends for different amounts of swirl.

Symposium (International) on Combustion, 1973
Combustion in high-speed swirling flow is an alternate process to the high-intensity, low-weight combustion chamber for gas turbines. The increase in combustion intensity due to the centrifugal force field, the more-rapid dilution, and the greater stability of the cooling film on the outer wall, are the main advantages of this system. Further, the high

Turbulent swirling reacting flow
32nd Aerospace Sciences Meeting and Exhibit, 1994Many combustion systems utilize the strong favorable effects of applying swirl to injected air and fuel, so aiding the stabilization of high-intensity combustion processes, and good flowfield characterization is of prime concern. The improvement and use of modeling work will complement and significantly reduce the cost of experimental development ...
