Neutral curve behaviour in Taylor-Dean flow

ZAMP Zeitschrift f�r angewandte Mathematik und Physik, 1987
Numerical investigations reveal a class of neutral curve in infinite Taylor-Dean flow not previously observed. Based on the work of \textit{P. Hall} [J. Fluid Mech. 124, 475-494 (1982; Zbl 0503.76054)], asymptotic expansions at the high-wavenumber end of the neutral curves are given. Previously, an interpretation had been given by \textit{D. C. Raney},

Dean Equations Extended to a Rotating Helical Pipe Flow

Journal of Engineering Mechanics, 2003
In this paper, the fully developed laminar flow in a rotating helical elliptical pipe is examined theoretically. This study focuses on the combined effects of the rotation, the curvature, the torsion, and the shape of cross section. The secondary flow and the fluid particle trajectory are discussed for different elliptical cross sections in the range ...

Stability of Taylor-Dean flow in an annulus with arbitrary gap spacing

Physical Review E, 1993
A linear stability analysis based on three-dimensional disturbances is implemented for the Taylor-Dean flow, a viscous flow driven simultaneously by a rotating inner cylinder and an azimuthal pressure gradient within an annulus with an arbitrary gap spacing.

Dean’s flow of aqueous solution of poly(ethylene oxide)

Korean Journal of Chemical Engineering, 1996
In this research the flow of Newtonian and drag reducing fluids through a helical tube,i.e.. Dean’s flow, was experimentally studied. The primary concern was to investigate the effect of added polymer on the secondary motion caused by the centrifugal force. The poiymer chosen in this study was poly(ethylene oxide) with the molecular weights of 300,000,

Hydrodynamic stability of Taylor–Dean flow between rotating porous cylinders with radial flow

Physics of Fluids, 2003
A linear stability analysis has been implemented for the Taylor–Dean flow between porous concentric rotating cylinders when radial flow is present. The stability equations with respect to both axisymmetric and nonaxisymmetric disturbances are derived and solved by a direct numerical procedure.

Stability of Taylor–Dean flow in a small gap between rotating cylinders

Journal of Fluid Mechanics, 1992
A linear stability analysis has been implemented for Taylor–Dean flow. a viscous flow between rotating concentric cylinders with a pressure gradient acting in the azimuthal direction. The analysis is made under the assumption that the gap spacing between the cylinders is small compared to the mean radius (small-gap approximation).

On the instability of taylor and dean flows under the influence of a circular magnetic field

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1961
On discute l'influence d'un champ magnetique circulaire sur la stabilite d'un fluide visqueux et conducteur de l'electricite en mouvement entre deux cylindres circulaires coaxiaux. Supposant que l'espacement entre les cylindres est petit par rapport a leurs rayons, on donne des resultats sur deux sortes de mouvement du fluide basique, produites par la ...
