摘要	For better understanding physical mechanism of radial disturbances, previously proposed to disturb the wake flow and vortex-induced vibration of risers, numerical simulations are carried out for the flow around the fixed cylinder with such disturbances at a Reynolds number of 100. After introducing disturbances, specific distributions of flow and vertical vorticity near cylinder surfaces are identified and related to different vortex patterns. The spanwise variation of free shear layers is discussed and physically explained. Different characteristics for the pressure on cylinder surfaces, frequency of vortex shedding and time history of lift are also analyzed and presented in detail.
