Mode Variation in Decelerating Taylor Vortex Flow.

Wave speeds in wavy Taylor-vortex flow

The speed of travelling azimuthal waves on Taylor vortices in a circular Couette system (with the inner cylinder rotating and the outer cylinder at rest) has been determined in laboratory experiments conducted as a function of Reynolds number R, radius ratio of the cylinders 7, average axial wavelength h , number of waves m, and the aspect ratio r (the ratio of the fluid height to the gap betwe...

Rayleigh–Taylor growth at decelerating interfaces

The Rayleigh–Taylor ~RT! instability is important in a number of research contexts. For the design or analysis of experiments and observations, it is often useful to know the growth exponent of an interface, even when the growth is strongly nonlinear. The growth exponent is defined here as the number of linear e-foldings by which initial perturbations at the interface would be amplified, if the...

Mode bifurcation control of a magnetic fluid on Taylor- Couette vortex flow with small aspect ratio

The study of Taylor-Couette vortex flow with small aspect ratio is great interesting. Additionally, the importance of magnetic fluids has been increasing in the engineering applications of various fields, and this leads to increase the interests to investigate the flow of magnetic fluids, which have the reactivity to magnetic field. Then Taylor-Couette vortex flow with magnetic fluids is expect...
