Abstract: Here we present a study on the Taylor vortices formed in a mineral oil between a rotating inner cylinder and a stationary outer cylinder. The apparatus is featured with a wide gap (radius ratio is 0.613) and a short liquid column (aspect ratio is 5.17). Particle image velocimetry (PIV) system was adopted to determine the position, shape and velocity distribution of the vortices. The experimental results show that the transition to wavy vortex flow occurs at a very high Reynolds number than in an infinitely long column, while an asymmetric feature was observed in the widths of the inflow and outflow regions. The simulation results from computational fluid dynamics (CFD) can satisfactorily reproduce the vortex structures, and the calculated maximum axial velocity agrees well with the PIV measurements. The effects of both the top and bottom ends on the vortex flow were also examined.
