Abstract
OpenFOAM and Aspherix simulation data for the paper, 'Assessment of coarse grained CFD--DEM modelling strategies in horizontal plug flow pneumatic conveying' The study examines the coarse grained (CG) CFD--DEM methodologies for plug flow pneumatic conveying within a horizontal, rigid and cylindrical pipe with periodic boundaries in the axial direction. We use coupled Computational Fluid Dynamics (CFD) -- Discrete Element Method (DEM) simulations to investigate the effect of different CG rules on four plug characteristics: velocity, length, porosity, and particle exchange rate with the stationary bed.
Spherical particles are used, and the CG rules are applied via the input scripts of the simulation cases. 9 simulation cases are provided, and these are at CG ratio=6. All the simulation cases in the paper can be created from the uploaded cases by varying the CG ratio or the smoothing length accordingly.
The simulation was run using 'CFDEMcoupling-Nonspherical-6.1.0' and 'Aspherix-6.1.0.' Aspherix is a proprietary software from DCS Computing and well recognized within Discrete Element Method (DEM) research community.
Each case folder includes the data produced from that simulation and the input files to re-run. The other simulation cases in the publication can be created by varying either the CG ratio from the .asx files in the DEM folders or the smoothing length from the couplingProperties dictionary in the CFD/constant folders.
In all simulations, plug flow pneumatic conveying is simulated in a horizontal and circular pipe using periodic boundary conditions. The flow solver is a slightly modified version of the "cfdemSolverPiso" of CFDEMcoupling. The implementation was done according to Eq. (21) of Hilton and Cleary (2011). The equation is also given in the submitted manuscript, so an interested reader can refer to the manuscript for more detail. This is done to enable us to input the pressure gradient as the momentum source in the periodic system.
