Boundary effects with a short annulus ofTaylor Vortex Flow (TVF) called Ekman boundary, are greatly related to the generation of the various modes in vortex structure, which is obtained even in the same Reynolds numbers. Some flows with these vortex structures are useful for cultivation of microorganism which is very weak in shearing flow, because it is said that a TVF has a mild flow characteristic even in higher Reynolds flows. In the present, the spatiotemporal velocity field in the higher Reynolds flow of TVF with a small aspect ratio is visualized and measured precisely by using ultrasonic velocity profiler (UVP) and discussed with the relationship between the flow structure and growth rate of the photo synthetic micro organism.
