Mixing Performance of an Agitated Vessel with Bottom Baffles

抄録

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 Nt_m 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.
