摘要:

通过适当地延长风洞的试验段长度,并利用尖塔、挡板、粗糙元等边界层发生装置,在4 m×3 m航空风洞中模拟建立了大气边界层流场,测量了模拟流场的平均风速剖面、湍流强度剖面、风谱等.结果表明:在4 m×3 m风洞中建立的模拟大气边界层流场适宜于建筑物风荷载、风环境模型试验.

Abstract:

By appropriately extending the length of the test section of the wind tunnel and using boundary layer generation devices such as minarets, baffles and rough elements, the atmospheric boundary layer flow field was simulated in the 4 m×3 m aviation wind tunnel, and the average wind velocity profile, turbulence intensity profile and wind spectrum of the simulated flow field were measured. The results show that the simulated atmospheric boundary laminar flow field established in a 4 m×3 m wind tunnel is suitable for building wind load and wind environment model tests.
