Abstract:
A combination of two models previously developed by Faran, and Atkinson and Kytömaa (Faran-AK model) was used to calculate the ultrasonic attenuation and the backscattering signal of a suspension of particles. The model of Atkinson and Kytömaa yielded the viscoelastic contributions while the model of Faran yielded the scattering contribution. A comparison with the more fundamental model by Epstein, Carhart, Allegra, and Hawley validated the combination, where the combination used here proved to be computationally less intensive and more stable. The Faran-AK model outputs were also compared with ultrasound measurements of glass beads with two different particle size distributions and varying concentrations. The comparison showed a very reasonable agreement of model and experiment.
