On the assessment of power consumption and critical impeller speed in vortexing unbaffled stirred tanks

Vortexing Unbaffled Standard Configuration (H=T; D=T/3). Comparison between experimental power number Np and proposed relevant correlations in sub- and super-critical regimes: grey squares, T=0.19m (visc=1100–78.8mPas); black squares, T=0.48m (visc 11.6–0.66mPas); open diamonds, T=0.19m, (visc 78.8–...
