  • Title: Clustering of inelastic soft spheres in homogeneous turbulence.
    Author: Burgener T, Kadau D, Herrmann HJ.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2012 Sep; 86(3 Pt 2):036321. PubMed ID: 23031027.
    Abstract:
    In this paper we numerically investigate the influence of dissipation during particle collisions in an homogeneous turbulent velocity field by coupling a discrete element method to a lattice-Boltzmann simulation with spectral forcing. We show that even at moderate particle volume fractions the influence of dissipative collisions is important. We also investigate the transition from a regime where the turbulent velocity field significantly influences the spatial distribution of particles to a regime where the distribution is mainly influenced by particle collisions.
