Abstract

Nonlinear 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 studied 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 multiphase 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 for microparticle extraction.
