Coherent Structures in the flow development region of a plane jet were investigated using the technique of flow visualization. For the flow visualization of the cross-sectional view and the three-dimensional view, the methods using fluorescent dye illuminated by a laser light sheet and a halogen light sheet were adopted. It was shown that the streamwise vortex, which has a counter-rotating vortex structure named rib-structure, is formed in the process of the development of the two-dimensional rollup of the instability wave in the flow development region.
