摘要
用实验方法研究了二维叶片前缘几何形状对气动性能和转捩的影响。实验是在低速叶栅风洞中完成的。考察了分别装有圆形和椭圆形前缘的一个NACA65叶型前缘附近的流动情况。给出了细致的叶片前缘和分离区内的压力分布情况。结果表明:前缘几何形状对前缘流动、分离和转捩及以后的附面层发展有很大的影响。
This paper presents an experimental study of the influence of 2d leading-edge geometry on behavior of separation bubbles. The measurements on a nose of enlarged blade were conducted on a special large-scale experimental facility, the pressure distribution of flow were measured. The test model used in this study consists of circular leading edge and elliptic leading edge. Results are presented for a range of incidence. The measurement result indicated that the leading edge shape has a large influence on flow details, separation and transition as well as the boundary layer properties after reattached point.
