Abstract
In this paper the numerical particulate flow model
EUgran+Poly (Schellander et.al, 2012b), which is an
Eulerian-Lagrangian and Eulerian-Eulerian numerical
hybrid model for dilute and dense rapid granular flows, is
modified to account for agglomeration. We introduce a
novel approach referred as, "Bus-Stop Model", where
agglomeration is modelled using Lagrangian tracer
trajectories. To achieve this goal, two possible
agglomeration models are presented: 1) a simple volume
balance model, 2) a new implementation of the population
balance model by Smoluchowski (Smoluchowski, 1917).
The validation of the new implementation of the
agglomeration model is done by comparison with the
discretized population balance model, for a simple case.
Furthermore the applicability of the model is shown for an
industrial cyclone. The agglomeration model shows the
mean particle diameter increases in the cyclone. The
simulation results indicate improved quality and accuracy.
