We performed the second stationary study at the resonance frequency that revealed the highest average acoustic energy density (1801 kHz). Taking both studies into account, we generated plots for the wall displacement (Fig. ), Gor'kov potential with acoustic radiation force as white arrows (Fig. ) and streaming velocity (Fig. ). The displacement plot shows that the maximal displacement of the wall is at half its height. At this point, a minimum of the Gor'kov potential (Eq. 2) is located. Thus, the acoustic radiation force (Eq. 1) is directed in positive y-direction throughout the entirety of the channel. Close to the wall, the direction of the force changes slightly towards the absolute minimum of the Gor'kov potential, which leads to an acoustic radiation force that pushes particles towards the thin wall.
