Taylor vortex flow appears between two concentric rotating cylinders, for example, fluid bearings of hard disks etc. It is important to investigate Taylor vortex flow in order to control flows. When the velocity of inner cylinder changes, the flow suddenly becomes unstable and develops into vortex flow having different number of cells. Cylinder torque applied to the cylinder walls and mean kinetic energy change sharply, leads to the deterioration and destruction of the container. In this study, the effects of cylinder length, angular velocity and, in particular, acceleration time of the inner cylinder, is examined in detail when cylinder length is almost identical to difference between the radii of inner and outer cylinders.
