We use two codes to perform discrete element modeling (DEM) at TotalSIM US. The open source code CFDEM-coupling supported by DCS Computing (http://cfdem.com/) and STAR-CCM+ Version 11.06 developed by CD-Adapco (http://www.cd-adapco.com/products/star-ccm).
To date, TotalSim has used CFDEM on two projects, A and B below and STAR-CCM+ on one project (B). We are currently conducting a comparison between CFDEM and STAR-CCM+ predictions for the heat transfer and particle spatial distribution for a single heated air jet fluidizing a bed of cooler particles in a small, well-defined compartment. The strengths and limitations of these software can be found in the following review file.
- Simulation of packing powder catalyst into a microchannel reactor using sonication
- Modeling of a large-scale, continuous peanut roaster
A select set of simple animations of LIGGGHTS and CFDEM simulations are described below and are available from TotalSim.
