The experimental results show that the definite separation of both modes appeared in wedge-shaped region downstream of the point source in accordance with the dispersion relation. It is also shown that the characteristic features of growing disturbances are in good agreement with the linear stability theory making use of the method of complex characteristics. In the last part of this paper, the reason is discussed why the stationary mode of the crossflow instability is prone to dominant appearance on rotating disk and swept wing compared to yawed circular cylinder., 資料番号: AA0001960006, レポート番号: NAL SP-43},
