| 摘 要： | 通过研究结冰风洞内常用的结冰气象参数标定方法，提出了适用于小型结冰风洞的简单标定方法。利用该方法对引射式结冰风洞内的液态水含量、水滴平均有效直径、云雾均匀性进行了标定，并在霜状冰条件下获得了试验冰形。对比试验冰形与数值计算结果可知，所采用的参数标定方法准确、有效，可满足工程实际要求。

Research on Calibration Method of Atmospheric Conditions in Icing Wind Tunnel |
| |
| Abstract: | Calibration method of atmospheric conditions in icing wind tunnel is investigated.An easy method for icing conditions calibration is proposed which can be applied to small icing wind tunnel.Icing parameters such as liquid water content,mean volume diameter of the water droplets,icing cloud uniformity are calibrated in injection driven icing wind tunnel.Experimental ice shape is measured in rime icing condition.Comparing tested results with numerical simulation,it is concluded that the presented calibration method is accurate and effective,which can satisfy the requirements of engineering application. |
