Abstract: Adding a splitter plate at the wake centreline of a bluff body is an efficient passive technique of controlling fully developed vortex shedding. In the present study, unsteady turbulent flow around a circular cylinder with a splitter plate is numerically studied with the finite-volume method in high Reynolds number range of 1.5×104

Key words: Circular cylinder, Splitter plate, Vortex shedding, Vortex-induced vibration
