Taylor vortex flow between concentric rotating cylinders, especially inner Cylinder is rotating and outer cylinder is at rest, in the symmetric end conditions was investigated by means of a flow visualization tequnique. The experiments have been performed on an apparatus of particular small aspect ratio to study the transition from Couette flow to Taylor vortex flow, from Taylor vortex flow to wavy Taylor vortex flow, and from wavy Taylor vortex flow to turbulent flow. Also the cell structure, the variance of cell height relative to Reynolds number, and the critical Reynolds number from Taylor vortex flow to wavy Taylor vortex flow were investigated. In the symmetric end conditions, there are only even number of cells but not odd number cells. And the structure depends on an aspect ratio. There are no difference of the variance of height between the upper and bottom cell. The critical Reynolds number from Taylor vortex flow to wavy Taylor vortex flow was revealed. This shows the stability of Taylor vortex flow.
