Abstract

The power consumption for a pitched blade paddle impeller in both baffled and non-baffled agitated vessels was measured over a wide range of Reynolds numbers from laminar to turbulent flow regimes. Power consumption for a non-baffled vessel was well correlated with the same correlation as that for a paddle impeller by modifying the coefficients in the correlation with blade angle. Power consumption in a baffled vessel was also well correlated with a correlation method similar to Kamei's one for a paddle impeller. The fully-baffled condition and the corresponding power number were presented by the following equations.<BR> (B_ω/D) n_b^0.8≥0.44N_pmax, _θ^0.2 (2θ/π) ^0.72<BR>N_pmax, _θ=8.3 (2θ/π) ^0.9 (n_p^0.7bsin^1.6 θ/d)
