Popis:	For a vessel agitated by the turbine-type impeller, the liquid flow and mixing in the bottom region were studied for comparison between conditions with and without baffles. Visualization of the flow and its measurement were done using particle tracking velocimetry. The flow along the bottom surface of the unbaffled vessel was observed to be more intensified than that of the baffled one. The related local energy dissipation was larger and the effective energy transmission was indicated for the condition without the baffles. For the unbaffled vessel, enhancement of micromixing near the bottom was demonstrated through a mixing experiment in a system involving chemical reactions.
