Acoustic streaming generated by standing wave in a rectangular resonator filled with viscous polytropic gas is simulated. Standing wave is excited by rotational vibrations of the lower boundary. The resonator is filled with small particles of water uniformly distributed over its region at the initial moment of time. In this paper the drift of the particles in resonator after a large number of periods studied numerically.
