Numerical simulation in the wind action analyses in silos with a windbreak

Resumo

A windbreak, by definition, is the planting of single or multiple rows of trees to reduce the wind speed to leeward. In this work, was analyzed the efficiency of windbreaks in attenuating the external pressure coefficients of wind action in silos. The methodology was validated using the Ansys Workbench software, considering a height/diameter ratio equal to 0.5. In other applications was studied the influence of the neighborhood on the external pressure coefficients and streamlines between geometrically identical silos. The significant reduction in external pressure coefficients was verified, highlighting windbreaks as an option to protect silos in open areas with high wind loads.
