Fractions of particles in the central subdomain, compared to the total number released, as function of their radius. These results are recorded at t = 16 s after particles release. In this case the acoustic energy density is kept constant around 106 Pa varying the displacement l0. (a) The frequency was kept constant at 1.9669 MHz, the resonance frequency of the reference system. (b) The frequency was changed for each AR to the resonance value and the displacement was varied obtaining an acoustic energy density constant.
