介绍了在8m×6m风洞第一试验段(12m×16m)一种地形的大气边界层模拟装置的设计、风洞流场校测试验。试验结果表明:模拟实现的流场品质(平均风速剖面、湍流强度剖面、湍流谱以及积分尺度等)完全可以满足桥梁试验要求的来流特性。
The design of a terrain modeling device for atmospheric boundary layer and the calibration of wind tunnel flow field are introduced in the first test section of 8m × 6m wind tunnel (12m × 16m). The experimental results show that the simulated flow field quality (average wind velocity profile, turbulence intensity profile, turbulence spectrum, integral scale, etc.) can fully meet the requirements of the bridge test flow characteristics.
