Dynamics of heavy particles in turbulent flows

Abstract

The dynamics of small, heavy particles as advected by a turbulent velocity field is an ubiquitous phenomena in Nature and industrial processes alike. In the context of a DEISA Extreme Computing Initiative (DECI) grant, we performed state-of-the-art numerical simulations of an homogeneous and isotropic turbulent velocity field at a resolution of 2048³ collocation points and with a Taylor Reynolds number R ¿ ~400. Along with the Eulerian dynamics we integrated the temporal evolution of an unprecedented statistics of more than 2 billions heavy particles. Heavy particles were modeled as "pointlike" spheres driven by Stokes drag and infinitely denser than the advecting fluid.
