Simulation of complex particle suspensions using coupled lattice Boltzmann-discrete element methods

摘要

This paper details the development of a computational model which is capable of direct numerical simulation of complex particle suspensions. The components of the model include the lattice Boltzmann method, the discrete element method, non-Newtonian rheology and turbulence modeling, and shared-memory, multicore parallel computations. Computational modeling of complex particle suspensions offers the ability to investigate flow characteristics which cannot be readily captured with experiments. In addition, the development of a validated computational model allows for the comparatively rapid and inexpensive evaluation of novel and or prospective fluid-particle combinations in silico.
