| 摘 要： | 基于FLUENT软件,采用标准湍流模型对防沙堤风场特征进行了数值模拟,研究了防沙堤迎风面和背风面设计方式对风场的影响。结果表明,防沙堤风场主要受迎风面坡度控制,坡度越陡对风速的衰减效果越好;对于固定形式的防沙堤,风场结构特征与风速无关,对不同风速的衰减比率是一定的。

| Abstract: | This paper elaborated on the simulation of the velocity around the sand-preventing dykes with different geometric parameters(l/h) of windward side and leeward side by k-ε model based on software FLUENT.The result showed that l/h of windward side had distinct effect on the velocity field,i.e.,the lower the l/h,the faster the wind velocity declined.As to the sand-preventing dykes that had similar size,the wind field was independent of wind velocity,and the reduction coefficient of a certain velocity was certain. |
