Onset of Turbulence in a Rotating Fluid

Light-scattering measurements of the time-dependent local radial velocity in a rotating fluid reveal three distinct transitions as the Reynolds number is increased, each of whic...

Dynamical instabilities and the transition to chaotic Taylor vortex flow

We have used the technique of laser-Doppler velocimetry to study the transition to turbulence in a fluid contained between concentric cylinders with the inner cylinder rotating....

Chaotic mode competition in parametrically forced surface waves

Vertical forcing of a fluid layer leads to standing waves by means of a subharmonic instability. When the driving amplitude and frequency are chosen to be near the intersection ...
