The bistable flow of two circular cylinders of diameter ratio 2:1 was investigated. Based on the quantitative and qualitative measurements, two modes of flow are observed. Interactions of the adjacent gap-side vortices with the outer vortices and the pairing of outer vortices in both modes form the important mechanisms for the development of flow structures and wakes further downstream.
