    Abstract

    Vortex shedding related with strouhal number cause to make inconvenience and fatigue problem. To improve these problems, rotatable wind fence is adopted. Rotatable wind fence breaks repeating of vortices caused by the unsteady separation of flow of a fluid around bridge girders. Rotatable wind fence works for reducing amplitude of vortex shedding.
