چکیده انگلیسی
The drift of incompressible particle in acoustic resonator with periodic shock wave is studied numerically. The computation schemes and algorithms are considered in details. The impact of main hydrodynamic forces on a drift direction is investigated. Simulations reveal the existence of threshold value of particle radius which divides drift regimes in two groups with opposite drift directions. For particles with radius more than threshold value inertia dominates causing drift to the center of resonator, where particle is trapped in some equilibrium zone. For particles with radius less than threshold value steady viscous drag dominates causing drift to the nearest boundary.
