Descripción
Buildings are commonly characterized by bluff and sharp edges bodies which lead to a very complex flow structure. Wind engineering conducts studies related to wind loads and flow field near walls, roofs and surrounding buildings to predict building behaviour under different weather conditions, so experimental tests are usually performed. The aim of this study is to characterize the flow structure around a building and minimize the possibility to be hazard to roof-mounted equipment. Passive flow control devices (CVG ? Columnar Vortex Generator) have been tested by modifying different geometrical parameters with the aim of reducing the adverse aerodynamic effects. Wind tunnel tests have been carried out to obtain experimental results. Particle image velocimetry technique has been used to provide quantitative information about the flow field. The best CVG configuration tested has presented encouraging results where the detachment angle has been reduced up to 71% with respect to the reference case. Furthermore, conical vortices mitigation at an incident yaw angle of 45° has been also investigated where a high reduction of the lateral vortices has been obtained.
