Dependence of the mechanism of solid particle drift in a nonlinear wave field on the time constant and wave front passage time

A criterion that allows determining the prevailing mechanism and direction of the drift of a solid spherical particle in a nonlinear wave field of a closed acoustic resonant cavity, depending on the ratio between the particle time constant, compression wave front growth time, and duration of passage of the acoustic wave, is analyzed. Particle motion is assumed to occur under the action of the Stokes force, buoyancy force, and virtual mass force.
