With existing numerical models for fluid particle systems in CHEM, the acoustic-particle interactions associated with two-phase dilute dispersed flow can be captured and the particle model can be validated using experimental and analytical data and verified using numerical techniques. The experimental and analytical data come from Zink and Delsasso and provides data for particles of diameters 5 to 15 microns for frequencies between 500Hz to 13600Hz. In the particle number density measurements by Zink and Delsasso there was a 10% estimated error range. Using the fourth order skew symmetric flux in CHEM and the built in Eulerian and Lagrangian particle models, the sound wave dissipation was captured and found to be within the margin of error. Two additional tests were conducted to measure the effect of nonlinear acoustics and increased bulk density on the dissipation. Nonlinear effects showed no significant effect and the linear increase in bulk density showed a linear increase in dissipation.
