In the present paper, fluid mixing process in a stirred tank with a newly designed conduit-type mixer has been investigated by the flow visualization and the concentration measurement. The results of the new conduit-type mixer are compared with a conventional fin-type mixer. Although the concentration measurement indicates that the mixing time by the conduit-type mixer is slightly longer than that by the fin-type mixer, the flow visualization shows that the conduit-type mixer generates the wider circulatory flow pattern and stirs the fluid over a vast area of the tank. Consequently, it is indicated that the conduit-type mixer has an advantage to stir the fluid uniformly in space.
