 note = {Characteristics of wavenumber of disturbance waves developing in three-dimensional boundary layer are examined using a complex ray theory which is established by an extended kinematic wave theory. The most important feature of this theory is that the propagation path of disturbance developing in the boundary layer can be determined uniquely and the N factor of e(sub N) method can also be expressed as a function of frequency and wavenumber. The purpose of the present study is to indicate the validity of this theory by comparison with the results of famous SALLY code and the 'envelope-envelope' method. Computations have been made for a flow around a yawed circular cylinder with sweep angle 50 deg. The velocity profiles are obtained by an approximate method of boundary layer calculation based on a similarity solutions. From this computation, it is found that there is no contradiction in the N factor among the results obtained by the complex ray theory and by the other methods. Furthermore, the frequency dependence of the wavevector is demonstrated from this method., 資料番号: AA0032827002, レポート番号: NAL SP-54},
