蛇行流における秩序構造の二断面同時可視化

Abstract

The coherent structure of turbulent meandering flow is investigated using the technique which visualize both streamwise and side views simultaneously by fluorescent injection method.The lifting wall streamwise on dye transport pattern, which is a large scale cohrent structure of turbulent meandering flow, are observed by streamwise and side views. It seems that these vortices are caused by the interaction between high speed fluid and large scale vortices near side wall.
