风洞不仅是航空航天发展的保证，也是风沙物理学研究的重要依托。对于风沙地貌、风沙环境的研究以及防护治理都有举足轻重的作用。以建设多通道风洞实验平台为背景，通过在UG中对平台进行建模，再利用商用软件ANSYS对三种不同进风口角度的风洞模型进行数值模拟分析，对比在三种不同角度情况下风洞实验段中的流体流线分布情况、流体速度矢量场分布情况及流体压力场分布情况，确定了最佳进风口角度的风洞模型，为后期建设提供了有力的技术支撑和理论基础。

Wind tunnel is not only the assurance of aerospace development but also rely greatly on the physics of sand blown .It has a pivotal role on aeolian geomorphology , and environmental research and protec-tion .This article is based on the background of the construction of multi -channel wind tunnel experimental plat-form, through the modeling of the platform in UG and using the commercial software ANSYS for numerical simu-lation analysis of wind tunnel model in three different inlet angles .Comparing the situation in three different an-gles of the wind tunnel test section of the fluid flow distribution , the fluid velocity vector field distribution and fluid pressure field distribution , the best inlet angle of wind tunnel model was determined , which provides strong technical support and theoretical basis for the later construction .
