Popis: It is possible to make motion of a paddle of the boat by using an oloid mechanism. It has been known that this is very effective for mixing water with small energy. However, the phenomena and the detail of the flow structure around the wings are not clarified yet. In order to investigate the flow and mixing process, the flow visualization technique is used for the visualization around tow disk type wings.The results by large particle tracer, air bubble and so on show that the characteristic feature of the flow is induced by large vortex ring and the separation at the edge of wing. These vortices cause the effective mixing of the water.
