Drift of a solid particle at longitudinal oscillations of gas in a tube

Drift of a solid particle is observationally explored at longitudinal up to-resonant oscillations of gas in the closed tube. It is revealed, that the oscillating particle in fields from the closed end up to centre of a tube moves in an axial direction to the piston with magnification of a vibration swing, and near to a wall to a reverse. It is shown, that in a radial direction drift of an oscillating particle occurs from an axis to a wall of a tube. Acoustic currents of gas in a tube cause such behaviour of a particle. It is revealed, that or lengths of a tube give magnification of frequency of excitation of gas in growth of a vibration swing of a particle and increase of its medial velocity.
