Taylor vortex flow appears between two concentric rotating cylinder for example, fluid bearings of hard disks, journal bearing and chemical reaction container etc. It is important for engineering to clarify the behavior of Taylor vortex flow In this study, the initial flow distributions between two rotating cylinders are changed, and the effects of the initial condition are examined. As a a difference was observed in the final mode depending on the difference of the initial flow condition. However, no regularities regarding the difference in mode formation were found and the tendency of the mode formation process was not specified. The processes of developing the vortex resulting in different final modes were monitored over time by visual observation. There was also a difference in the time taken for the flow to reach the steady state. In each mode formation processes, kinetic energy is compared.
