本文采用 PIV技术中的流态显示方法 ,对大攻角翼型绕流的流场进行多次曝光流态显示试验 ,获得了丰富的流动信息。本文同时应用 CFD技术 ,进行了相应的数值计算研究。结果表明 ,试验与计算获得非常好的一致 ,两者得到一次相互验证 In this paper, we use the flow display method in PIV technology to test the multi-exposure flow pattern of the flow field around a large angle of attack airfoil, and obtain abundant flow information. In this paper, the application of CFD technology, the corresponding numerical study. The results show that the tests and calculations are very consistent and the two are validated one at a time
