Wind Tunnel Test on the Effect of Width of Windbreaks on the Wind Speed Distribution in Leeward

Abstract

Model tests of windbreaks were carried out in a wind-tunnel to make clear the effect of width of a windbreak on the wind speed distribution in leeward. The drag force on windbreaks was measured using a drag meter in a wind tunnel and utilized as an index of the aerodynamic properties of the windbreaks. The results show that the patterns of the wind speed distribution in leeward are influenced significantly by the width of windbreaks.
