A cylinder rotating around horizontal axis was put on a table rotating around vertical axis. The cylinder diameters and aspect ratios were changed, and the shapes of vortex in rotating cylinder were observed when the speeds of rotating table and rotating cylinder were changed. It was found that there were some patterns of vortex shape, which depended on the aspect ratios and Rossby number. The shapes of vortex were also studied with computer simulation of flow pattern, and they almost accorded with the experimental results.
