Therefore, the effect of interfacial shear on criticalwave velocity is clearly different under different Reynolds number.
剪切力对临界波速的影响在不同雷诺数下也有所不同。

Physically, at a special criticalwave speed the flow may have a naturally periodical separated-reattached pattern, with each wave trough capturing a stable vortex ring.
The neutral stability curves and the character parameters are given, including the temporal and spatial growth rate, the criticalwave number, the maximum wave number and the wave celerity.
