This study investigates a wind-shear mitigation method for improving wind turbine performance by modifying a vertical wind profile projecting to an MW-class wind turbine. A Computational Fluid Dynamics software, FLUENT, is used to simulate the characteristics of steady/unsteady wind flow over a shear-free structure installed upstream of a wind turbine. The shape of the shear-free structure can be a fence, buildings and wind break trees, and such like. According to the results of the numerical simulation, it is obvious that wind shear between the heights of a wind turbine rotor-plane is noticeably mitigated due to the speedup effect on a virtual hill generated by flow separation behind a shear-free structure.
