AIRFLOW AROUND ARTIFICIAL WINDBREAKS WITH ELASTIC SUPPORT
A 3D numerical simulation was performed regarding the airflow around a windbreak permeable panel at two different inclinations. The inclined panel was studied as a snapshot of an elastically supported windbreak rotating around its base. In this way the sheltering effect of such an elastically supported windbreak was investigated. A permeable agricultural net with porosity ratio equal to 62% was selected as the windbreak cladding material. Wind velocities normalized with respect to a reference upstream position are presented for different locations and heights windward and leeward of the panel in order to visualize the airflow pattern. The numerical results were validated by full scale tests. For the full scale experiments the elastic support function of the panel was achieved by using appropriate extension springs.
