Abstract

New GPU-based computers and new algorithms enable researchers to perform numerical simulations of particulate flows in which the particles are resolved and the hydrodynamic forces on them are obtained from first principles rather than from correlations. One such method will be briefly outlined and then several applications described: kinematic waves and the statistics of various quantities in a fluidized-bed-like system, the behavior of tetrads (four-particle groups), the rotational dynamics and thermal wakes of particles immersed in an incident turbulent flow and others. This work will be placed in the context of existing methods and will be motivated by outlining some outstanding problems in this general area. The promises and obstacles of the paths opened by this general area of research will be described.
