The present paper presents the rotating instability around a rotating cylinder between two coaxial stationary circular disks experimentally and numerically. In the experiment, the hot-wire measurements were conducted. In the simulations, the calculations were performed which are corresponding to the experimental setup. The experimental and numerical results shows qualitatively good agreements with respect to the velocity fluctuations. These results indicate the rotating instability of one cell rotating in the circumferential direction.
