Description

Windbreak nets are most often used to prevent agricultural wind damage, since they are cheap and easy to install. However, little is provided concerning the dynamical characteristics of such windbreak nets, hampering the design of windbreak planning through the quantitative use of the latter. We measured both dynamical characteristics and wind fields around popular five windbreak materials using a wind tunnel. Subsequently, we tried to simulate the measured wind field using a numerical atmospheric model. The measured wind fields show various flow patterns around windbreaks well known in literature, with recirculating eddies for two spunbonded fabric windbreaks. The relationship between the wind field patterns and porosities of the windbreaks is more or less the same as in past studies, while the numerical simulations reproduce wind fields around the three popular windbreak nets fairly well. It is confirmed that the wind tunnel measurements and numerical simulations are reliable means to reproduce realistic wind field around popular windbreak nets.
