基于CFD的树高与风速风压关系的模拟

A CFD-based Simulation of the Relationship between Tree Height and Wind Velocity and Pressure

为了解树高与风害的关系,基于CFD的模拟思路,以橡胶树为模拟对象,利用GAMBIT,FLUENT,CFD-POST 3个软件,模拟不同树高下与风速、风压的关系。结果表明,树高与风速、风压成正相关关系;树高每增加3 m,风速平均增加7.7%,风压平均增加15.8%。

Typhoon is a frequent natural disaster attacking rubber plantations in Hainan,China. In order to understand the relationship between tree height and wind damages to rubber trees three softwares,GAMBIT,ANSYS（ FLUENT） and CFD-POST,were used to simulate and analyze the varying relationships between wind velocity and wind pressure with the rubber tree height as a basis. The result showed that the rubber tree was positively correlated with wind velocity and wind pressure. For each 3 m increase in tree height the wind velocity and the wind pressure increased by 7. 7% and 15. 8%.
