Abstract

Taylor vortex flow between two concentric rotating cylinders appears in a journal bearing or the chemical reactors. It is useful in the engineering point of view to analyze the behavior of the flow. The governing parameter of the flow are the aspect ratio and Reynolds number. The aspect ratio of the cylinder height to the gap between the inner and outer cylinders. Reynolds number is defined using the speed of the inner cylinder. In this study , Taylor vortex flow at small aspect ratio is analyzed by using PIV method. The flow structure is investigated quantitatively. The PIV results are compared with the results obtained by the numerical method.
