Abstract
We investigate the stability of oil-water layered systems at arbitrary values of physical parameters. It is essential to distinguish the known electric-hydrodynamic instability from parametric resonance. Parametric resonance in layered systems under alternating current shows the presence of two frequency bands which differ in behavior of foreign charge storage. We report numerical experiments on the nonlinear behavior of parametric resonance in layered systems subject to acoustic excitation. Periodic pulse impact on the boundary of a layered system causes an increase of several orders of magnitude in the amplitude of its elastic stress relative to the initial distribution.
