Several new parcel release methods are available when using unsteady particle tracking. These allow you to specify the number of particles per parcel, the mass of the parcels, or the diameter of the parcels. ( Steady/Transient Treatment of Particles ) Node based averaging is now available as a...

The dense discrete phase model (DDPM) is a Lagrangian parcel-based approach that models particle collisions and uncorrelated translations using the kinetic theory of granular flows (KTGF). This approach has numerous advantages over the Eulerian two-fluid model (TFM). These include better resolution ...
Avoids small cells for tiny inlets which requires small DDPM parcels leading to impractically large mesh and parcel count Advanced Drag Laws for Granular Materials EMMS, Filtered, Gibilaro and Huilin-Gidaspow drag laws Benefit: Increased accuracy for granular materials 27 Ansys CFD Coupling (Fluent)...
Enhancement request is now in the system, so you'll have to wait for the "easy" option. Short term you may be able to use a UDF or some other reporting option, but it may not be straightforward: you'll need parcel mass & impact velocity for a start. November 16, 2020 at 9:50...

The ideal air entered the filtering chamber at a certain velocity from the velocity inlet, exited the clean chamber through the pressure outlet, and pressure measurement points were set in the middle of the filtering and clean chambers to monitor pressure drop changes during the filtration process....
