Impeller Clearance Effect on Off Bottom Particle Suspension in Agitated Vessels
Date of Original Version
The effect of impeller off bottom clearance on the power input requirement for off bottom solid suspension was examined for 45° pitched blade impellers in flat and round bottom fully baffled agitated vessels. Results showed a similar dependence as obtained for radial flow impellers when similar flow patterns were observed. The dependence appears to be independent of the impeller diameter to tank diameter ratio and vessel shape. © 1987, Taylor & Francis Group, LLC. All rights reserved.
