Three-dimention structures in the vortex street wake of a two-dimention bluff body mean two types of structures. One is three-dimensionality for a lateral vortex shed from a two-dimensional body, another is three-dimensionality structure wound around a lateral vortex, such as longitudinal vortex. The purpose of this study was to investigate these two types of three-dimensional structures in detail by flow visualization. As the results, these two types of three-dimensional structures were classified based on Reynolds number and aspect ratio of body, three-dimensionality for a lateral vortex was shown quantitatively.
