| 内容記述 | By use of a Fourier transform and an expansion in power series of disturbance amplitude, a momentum equation is reduced to a non-linear parabolic differential equation for the disturbance amplitude. Non-linear effects are considered to the third order of the amplitude. Disturbance energy is assumed to be concentrated in the most dangerous modes, which have wave numbers close to the wave-number corresponding to the largest temporal growing rate selected by a linear stability theory. It is explained that the disturbance energy must be distributed within the very narrow range of the wave-number for obtaining the amplitude equation. The amplitude equation is similar to the equation already known, though the equaion in this analysis has the interactions between low wave-number modes and the most dangerous modes. For the subcritical case, the unstable equilibrium amplitude is examined by means of numerical calculations. | |||||||
