    Abstract

    Three-dimensional wake transitions of an isolated circular cylinder, a circular cylinder with a near-wake wire disturbance, and a circular cylinder placed near to a moving wall are investigated using direct numerical simulation. The evolutions of the wake flow structures with time and the Reynolds number are examined, and corresponding variations in the flow three-dimensionality, vortex shedding frequency and hydrodynamic forces are investigated. The fundamental physical mechanisms responsible for the observed flow characteristics are also explored.
