Unaerated and aerated power and mixing characteristics were studied in two agitated vessels. In one of 56cm diameter (T 56) single impellers with a liquid height giving an aspect ratio AR of 1 and dual and triple 1 impellers (AR = 2) were used in the turbulent region. In the other of61cm diameter (T61), only single impellers at AR = 1 were studied in water and viscous, non-Newtonian sodium carboxymethylcellulose (CMC) solutions, the latter giving Reynolds numbers in the transitional regime. The axial flow hydrofoil impellers used were APV-B2's (B2-30U, B2-30D and B2-45U) and Lightnin' A-315D and A-315U (U - up-pumping; D - down-pumping). Mixing times and homogenisation were also measured in T56 using a decolourisation technique for dual and triple impeller configurations of APV -B2's under unaerated and aerated conditions. The results are compared with radial 6 blade Rushton turbines (6RT).
