　　由于模型尺寸与实验风速的限制，低速翼型风洞实验雷诺数通常小于实际值，造成翼面转捩点偏后，翼型表面流动与实际不相符。为了尽量真实模拟实际流动，风洞实验一般采用粗糙带在翼型表面前缘进行固定转捩。实践表明，粗糙带的种类及其参数对实验结果有重要的影响，需要非常仔细地选择。另外，由于风力机叶片长期在野外工作，污染造成表面粗糙度增加，这部分的影响一直没有得到很好的研究。本文采用风洞实验的方法，对ZZR、ZZT、T和H型等四种粗糙带在风力机翼型风洞实验中的作用及附加影响进行了研究。研究结果表明，在风力机翼型实验中，ZZT型具有转捩效果好和附加阻力小的特点，H型则对昆虫尸体的影响有较好的模拟效果。

Due to the limitation of model demension and experimental speed, the experimental Reynolds number in the low speed wind tunnel is usually less than the practical value of airfoil section of wind turbine. This will make the transition location difference between experimental and actual situation. For the purpose of simulating real condition, fixed transition performed with transition tape is often adopted in wind tunnel experiments. Practice shows that the types and parameters of transition tape have an important impact on the experimental results. It needs to be chosen very carefully. In addition, because the wind turbine blade operated in the field for long time, contaminations accumulate on it and increase its surface roughness. This contamination has a great role on the rotor performance; the impact of it has not been well studied. This paper gives a summary of wind tunnel test results and discusses the actions of four types of transition tape of ZZ,ZZT,T and H, and additional effects on the wind turbine airfoil section. The results show that ZZT-type has well transition effect with the least additional drag and H-type has a better simulation for the impact of the insect compacts in the wind turbine blade airfoil experiment.
