Numerical simulation of flow fields through porous windbreak in shrubby zone

Abstract

Abstract: By treating the windbreak and shrub with the parameters in a equation, the flow fields through porous windbreak with and without shrub were calculated. The changes in relative wind velocity in horizontal direction, velocity profile and turbulent energy of the section were compared. It is concluded that shrub was very important in windbreak system, which could decrease the wind velocity in front of or some distance in the leeward of the windbreak. The calculated numerical results were compared with the data from wind tunnel experiment where the influence of shrub on flow field was analyzed.

Key words: Windbreak, Shrub, Numerical simulation, Relative velocity, shallow lake, regional heterogeneity., altitude, cladocera, nutrient level
