摘　　要：以表面热膜法和红外图象法作为主要方法，以油流法和荧光微丝法作为辅助方法，在低速风洞中，对三维边界层转捩现象进行了实验研究。An experimental study is performed on 3 D boundary layer transition phenomena. Four different methods infrared images, surface hot film gages, oil flow and fluorescent microtuft are compared using the same model of a yawed wing for the same wind tunnel conditions. The experiments are carried out in a low speed wind tunnel. Through the analysis of experimental results, a practicable method to locate the 3 D boundary layer transition is developed.
