• 0405 Spectrum Analysis of Oscillatory Field in Chaotic Taylor-Couette Flow at Low Aspect Ratio

抄録

A Taylor-Couette Vortex Flow has a mild mixing effect even in high rotating speed with the inner cylinder. This effect is expected to be applied new bio-reactor system where the micro cells are damaged by strong share flows. Furthermore, in the case of small aspect ratio, this vortex has characteristics such as the different vortex structure, because of the Ekman effect in the top and bottom boundary layers and the acceleration of the inner cylinder. However, this vortex flow mechanism like a chaotic flow has not been investigated much. The purpose of this study is to understand the flow mechanism from a numerical analysis. In this report we mainly analyzed the process of transition to turbulent flow by direct numerical simulation.
