EXPERIMENTAL INVESTIGATION OF TAYLOR INSTABILITY USING NON-NEWTONIAN FLUIDS.
Abstract
The critical Taylor numbers for five different non-Newtonian solutions were determined experimentally by visual observation using the hydrogen bubble technique. Contrary to a finding by others, the present experiment indicates that the critical Taylor number is decreased as the concentration is increased. The shear on the outer cylinder due to rotation of the inner cylinder was also measured for an intermediate range of Reynolds number. Substantial reductions of frictional drag coefficient were achieved at higher additive concentrations when the comparison was based on equal Reynolds number. (Author)
