Abstract
Based on laser Doppler anemometry, the mean and fluctuating components of the flow of a non-Newtonian shear thinning fluid in the transition regime in a vessel agitated either by a narrow or a wide blade axial flow hydrofoil impeller are presented for the first time. Comparison with similar measurements for water (fully turbulent flow) shows that the flow is confined much more to the impeller region and that the flow numbers are some 15 to 35% lower. The fluctuating velocity components were 20 to 50% lower. The total radial-axial circulation flow was also estimated and used together with the impeller power to show that the efficiency of the narrow blade hydrofoil was significantly higher.
