Non-linear small amplitude high frequency vibrations affect mechanical systems leading to such effects as the stabilization of an inverted pendulum on a vibrating foundation and size-separation of particles of a granular material. These effects can be studies using the mathematical technique called the method of separation of fast and slow motions. When applied to fluid mechanics applications, the method predicts various unusual effects including jamming holes in a vibrating tank with liquid, vibrational propulsion, and multi-phase flow separation. Many of these effects have been confirmed experimentally. Here we discuss the possibility of similar microfluidic effects in applications where capillary forces dominate over viscosity and inertia, such as vibrational aeration, vibration-induced superhydrophobicity (the elimination of the contact angle hysteresis) and vibrational two-phase flow separation.

适用于涉及润湿，超疏水性和微粒提取的应用的振动运动分离方法

非线性小振幅高频振动会影响机械系统，从而导致诸如倒立摆在振动基础上的稳定和粒状材料颗粒的尺寸分离之类的影响。可以使用称为快动和慢动分离方法的数学技术来研究这些效果。当应用于流体力学应用时，该方法可预测各种不寻常的影响，包括在振动罐中因液体堵塞孔，振动推进和多相流分离。这些作用中有许多已通过实验证实。在这里，我们讨论了在毛细力主导粘度和惯性的应用中，例如振动曝气，
