基于CFD的高校宿舍区室外风环境模拟分析和优化设计

Simulation Analysis and Optimization Design of Outdoor Wind Environment in College Dormitory Area Based on CFD

为分析校园宿舍区内风环境优缺点并提出优化方案,参考以往气象资料,利用CFD软件PHOENICS对宿舍区内风环境进行仿真模拟,分析模拟结果得知,宿舍区风环境整体稳定,但存在高速拐角风、大面积风影区等问题。针对以上问题,提出在宿舍区西、西北、东南方向布置绿化、设置导风板等措施改善风环境,并就优化后的宿舍区再次进行模拟。结果表明,优化后的宿舍区风环境有较大提升,场地内风环境各项参数更加合理。

In order to analyze the advantages and disadvantages of the wind environment in the campus dormitory area and propose an optimization plan,referring to the past meteorological data,this paper uses CFD software PHOENICS to simulate the wind environment in the dormitory area.The analysis and simulation results show that the wind environment in the dormitory area is stable in overall,but there are problems such as high speed wind corners,large areas of wind shadows and other problems.In response to the above problems,measures such as arranging greening and installing wind deflectors in the west,northwest and southeast of the dormitory area are proposed to improve the wind environment,and the optimized dormitory area is simulated again.The results show that the optimized wind environment in the dormitory area has been greatly improved,and the various parameters of the wind environment in the site are more reasonable.
