Abstract
The period-doubling route to chaos for a swirling vortex flow in an open cylindrical container, at an aspect ratio of 2, driven by a rotating bottom disk was recognized by using laser-Doppler velocimetry. The onset of periodic motion for the flow was found when Re was in the range between 1850 and 1900. The flow was subharmonically bifurcated into a double-period motion when Re was about 2150. When the Reynolds number was in the range from 2300 to 2400, the flow bifurcated again through the period-doubling mode. When the Reynolds number was further increased, the flow eventually showed chaotic motion. The existence of a free surface promotes the onset of periodicity, and the difference of the critical Reynolds number with and without a free surface was estimated to be about 600. © 1995 Springer-Verlag.
