Abstract:
This study of the flow between a rotating inner and stationary outer cylinder revealed secondary vortex flows at Taylor numbers well below the value at which Taylor vortices are formed. A distinct sequence of transitional stages has been observed. Torque measurements, visual observations, and varying the eccentricity have been used to study sub-critical vortices with zero axial flow
