结合风洞试验测试对Irwin探头的制作、标定以及使用进行分析,并采用自制的Irwin探头和简便风向测试设备对某群体建筑行人区域风环境进行了研究,结果表明:经标定使用有机玻璃制作的Irwin探头具有很好的线性度,可以得到相对准确的行人高度风速,考虑到压力测试设备的精度,应当在尽量高的风速下测试;采用拍照方式记录的风向标基本上可以得到行人高度处的风向信息;由于狭管效应与角区气流加速效应,实例群体建筑夹缝与角区的风速比较大,风环境问题突出,需要采用风环境改善措施降低该区域风速;另外通过对200名志愿者的测试对行人舒适度的阀值进行了讨论。
Combining with the wind tunnel test, the Irwin probe was fabricated, calibrated and used. The homemade Irwin probe and the simple wind direction test equipment were used to study the wind environment of pedestrian in a group of buildings. The results show that the calibration of the Irwin probe Irwin probe with good linearity, you can get a relatively accurate pedestrian height wind speed, taking into account the accuracy of the pressure test equipment, it should be tested in the wind speed as high as possible; recorded by means of photo-taking wind vane basically get the pedestrian height at the wind direction Information; due to the narrow tube effect and the acceleration effect of the corner area airflow, the wind speed in the case group colony and the corner area is relatively large, the wind environment problems are prominent, and the wind environment improvement measures are needed to reduce the wind speed in this area. In addition, The threshold of pedestrian comfort is discussed.
