Numerical simulation interaction of aerosol particulute agglomerates in acoustic field

Abstract

Acoustic agglomeration is a process in which intense sound waves produce relative motions among fine mostly the micron-sized solid aerosol particles, where they touching each other form agglomerates. Acoustic agglomeration has recently been the focus of theoretical and experimental research to increase agglomeration efficiency of micron-sized particles. The understanding of particle behaviours in particulate flows is interesting from environmental engineering and theoretical points of view. The authors will demonstrate in this study the potential of DEM to analyse acoustic wake agglomeration, to improve the understanding of the acoustic wake between two particles. Interaction of mono and poly-sized spherical microparticles in the presence of gravitation is addressed. The uthors will employ this study in future works, for the analysis of multy-particle acoustic agglomeration.
