摘要
采用风洞实验结合数值模拟方法研究沙漠公路近壁流场,进而探讨沙漠公路的防沙优化设计.建立了模拟风场结构的二维湍流模型,借助Fluent软件进行计算,与风洞模型实验进行对比,并由此模拟计算不同公路设计条件,比如公路边坡比、宽度、高度以及风向与公路走向夹角等不同条件下公路附近的流场结构.
The paper provided the governing equations for the flow fields near highways and succeeded in reproducing the experimental results by numerical simulation method, on this basis, presented the distribution law of the wind field near highways a,nd drew the conclusion that there is an influence on the flow from the slope ratio, the width, the height of the roadbed as well as from wind direction.
