Flow Visualization Around An Array of Small Wind Turbines Installed on the Building

Abstract

This paper describes a study of integrated small wind turbines for the built environment. In order to create the amenity space, the prediction of the wind flow is important to evaluate the windbreak deficit effect and turbulence in the wake. In the work, flow field around a building, on which a integrated wind turbines system installed are investigated by using model wind turbine. Result indicates the remarkable effect of the integrated system on the flow regime in the wake. If the array was installed behind the separated flow that was induced at the building corner, the strong shear flow was weaken by the array. By designing the optimum layout, it is able to eliminate the separated flow near the building.
