| 摘 要： | 为研究风力机叶片的结冰特性与防除冰方法,设计了一种简便、低成本的结冰风洞实验系统。利用北方冬季的自然低温条件,将常规的开口射流风洞加以改造,安装水雾喷射系统和结冰测试段以提供结冰环境条件。在冬季进行了结冰验证实验,对结冰风洞的3个主要参数:温度稳定性、液态水含量和过冷水滴平均直径进行了测试和标定。结果表明,在环境温度相对稳定的冬季时间段内,主要指标可在一定程度上满足风力机结冰实验要求。

Design of wind tunnel experiment system for wind turbine icing by using natural low temperature |
| |
| Abstract: | A simple and low cost icing wind tunnel experiment system has been designed in or-der to study the characteristics of wind turbine blade icing and de-icing methods.The convention-al open j et wind tunnel has been transformed by using the natural low temperature condition of the northern winter,and a water spray system and the icing test section were installed to provide the icing conditions.The verification experiments were carried out in winter,and the three main parameters:the temperature stability,the liquid water content and the medium volume droplet diameter were tested and calibrated.The results show that the main indexes can meet the re-quirements of the wind turbine icing test to a certain degree at the relatively stable environment temperature. |
