The method of calculating the solitons which put forward by Kruskal and Zabusky has played an important role in the development of the soliton theory,however,numerous numerical results show that even though the parameters satisfy the linear stability,nonlinear instability will also appear.

Experimental Investigation on Instabilities of Steam-Water Two-Phase Flow in Large L/d Inclined Parallel Upward Smooth Pipes;

The studies show that different types of the oscillation modes of the pulsational instabilities arise from the coupling of radial perturbations to azimuthal perturbations and the vertical perturbations.

The tank was of comparably small thickness and the turbulence subsequent to the instabilities was pseudo-3D.
