Wake structure behind an NACA0012 with no incidence was examined to scrutinize the frequency selection mechanism of growing disturbances at Re = 7,200 based on the wing chord and the free-stream velocity. Two different kinds of unstable disturbances, which exponentially grow in space, were observed. The minor disturbance is due to convective instability, while the origin of the major one may be attributed to absolute instability. Theoretical comparison is necessary to identify these disturbances.
