In a study of a flow caused by a rotating disk in a casing, as for many of past studies, most of the form of the rotating disk is not considered. However, it became clear by the study of late years that a radial gap affected the flow between the casing base and rotating disks greatly. In this study, we used the rotating disk having different forms and changed the size of the gap in the cylinder casing and tested it about the influence that the radial gap gave to the flow near the fixed disk. As a result, it has been observed that "bead-like-vortex" is generated in a disk. "Bead-like-vortex" is investigated in detail and the result of the experiment and PIV analysis is shown in this paper.
