Abstract
In order to clarify the flow structure generated by Oloid wing, which is constructed by two circular disks, the flow velocity field is visualized and also is measured by a small velocimetry, a conventional propeller type one. In the previous two reports, it was found that the vortex ring can travel far away and it would be effective for mixing phenomenon. This paper deals with the measured flow rate, the entrainment rate, mixing time and so on. From the point of view as the fluid dynamic, the effectiveness of the mixing, these are examined in detail.
