Granular flows are present in numerous industrial and natural processes. To study these flows, we use the Discrete Element Method (DEM) which, despite computational advances, leads to simulations that are costly in terms of computation time. <\/p>\n\n
In this context, we propose a new method aimed at significantly reducing computation time. The main idea is to extend an existing approach based on the pseudo-periodicity of processes. After a short DEM simulation (a few periods), the results are extrapolated to long times. <\/p>\n\n
This approach enables the modeling of heat transfer in DEM simulations (without interstitial fluid) and CFD-DEM (with interstitial fluid). The extrapolation algorithm we have developed handles two types of heat transfer: conductive and convective. It can be extended to radiative transfer as well as to other transport phenomena such as the transport of chemical constituents.
This work constitutes a first step toward low-cost numerical simulation of large-scale industrial processes. Our ultimate objective is to achieve a fast simulation method, applicable macroscopically, to study all types of reactive granular flows such as in rotary kilns, mixers, and fluidized beds. <\/p>\n","protected":false},"excerpt":{"rendered":"
