In a previous study, acoustic waves were shown to have the potential to induce grouping of particles in exhaust systems [1]. In the present study, three-dimensional CFD simulations of single isopropanol droplet streams moving in air subjected to an acoustic field were performed with ANSYS Fluent. The Eulerian-Lagrangian approach was utilized based on the classical work of Gor'kov [2, 3] with the generalization of Settnes and Bruus [4]. The simulations reveal a grouping dynamics behavior of the droplets in acoustic standing waves (ASWs). The distances between the droplets in the stream are mainly affected by the droplet residence time which is the time a droplet spends in the ASW. The grouping dynamics also depend on the number of pressure nodes in the field.
