Abstract

The mixing performances such as the flow pattern, the mixing time and the velocity profile, were measured in a vessel with bottom baffles. The bottom baffles induced high velocity from bottom to surface at the center of the vessel. The dimensionless mixing time Ntm took the minimum value at the bottom baffle diameter being 0.83 times as large as the impeller diameter, regardless of the baffle plate configurations and width.
