北京交通大学大气边界层风洞为双试验段回流式闭口风洞。其中,高速试验段尺寸为3.0m(宽)×2.0m(高)×15.0m(长),最大试验风速为40m/s;低速试验段尺寸为5.2m(宽)×2.5m(高)×14.0m(长),最大试验风速为18m/s。第三方评测机构对风洞进行的流场校测表明,湍流度、风偏向角和速度不均匀性等各项指标均很好地达到了相关技术标准要求,可用于建筑、桥梁等结构的测压、测振实验
Beijing Jiaotong University atmospheric boundary layer wind tunnel is a double experimental section of the return-flow closed-mouth wind tunnel. The size of the high-speed test section is 3.0m (W) × 2.0m (H) × 15.0m (L) and the maximum test wind speed is 40m / s. The low-speed test section has dimensions of 5.2m (W) × 2.5m 14.0m (long), the maximum test wind speed of 18m / s. Third-party assessment of the wind tunnel conducted by the field test shows that the turbulence, the wind deflection angle and speed and other indicators of non-uniform well to achieve the relevant technical standards, can be used for construction, bridges and other structures of the test Pressure, vibration test
