Although it is generally known that the Karman vortex street consists of large-scale vortex structures with three-dimensional characteristics, the causes of three-dimensional instability have not yet been elucidated. In this study, the flow of the separated region over a circular cylinder was observed by using the laser light sheet technique in the Reynolds number range of 230 to 1340 in a towing water tank. As a result, it was determined that the three-dimensional features of laminar boundary layer separation over a circular cylinder were characterized by the recirculating flow in the separated region. The relationship between three-dimensional instability and Reynolds number was investigated.
