mean velocity point
解釋
平均流速點-
The instability in the natural convection boundary layer initiates with the buoyancy eigenmode and develops into non - linear stage with the turbulization of the buoyancy eigenmode. in the mean time, the invisid eigenmode at the inflexion point appears and begins to increase at the outer layer. experimental results show that the turbulent layer near the maximum velocity point can be detected while the reformed grashof number
自然對流邊界層的穩定性由浮力振型失穩開始，並隨著浮力振型的湍流化進入非線性階段，與此同時，無粘性振型在外層開始失穩。實驗結果表明，修正格拉斯霍夫數grashof -
A high frequency secondary instability mode is detected, which rides on the primary instability wave in time domain and appears at the inflectional point of mean streamwise velocity profile
結果表明，高頻二次不穩定性在時域上表現為騎在基頻波的特定的相位區域。
