Electrochemical analysis of Taylor vortices
Steady Taylor vortices in the annular gap between coaxial cylinders were studied using the electrodiffusion method. The cylinders had an aspect ratio of 17.7 and a radius ratio of 0.5. The inner cylinder was driven with a stepping motor. The Reynolds number was in the range (113, 880). Two three-seg...

| Summary: | Steady Taylor vortices in the annular gap between coaxial cylinders were studied using the electrodiffusion method. The cylinders had an aspect ratio of 17.7 and a radius ratio of 0.5. The inner cylinder was driven with a stepping motor. The Reynolds number was in the range (113, 880). Two three-segment circular probes were imbedded with a horizontal shift of 5 mm in the wall of the outer fixed cylinder. The vortexes were swept along the probes by a slow upwards axial motion of the electrolyte solution. The axial distribution of the axial and azimuthal components of the wall shear rate was obtained and fitted by sixth-order Fourier series. The torque was calculated from the azimuthal component. The vortex ascending velocity and vortex height were evaluated from the correlation and autocorrelation functions of the measured current. |
