Characterising vertical plug flow pneumatic conveying using CFD-DEM

OpenFOAM and Aspherix simulation data for the paper, "Characterising vertical plug flow pneumatic conveying using CFD-DEM". It contains the full simulation data of the "base case", which corresponds to Section 4.1 of the paper. Also, the input files of the base cases of the parametric study sections, Sections 4.2 and 4.3 are also provided. 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 recognised within the Discrete Element Method (DEM) research community. In this simulation, plug flow pneumatic conveying is simulated in a vertical and circular pipe using velocity inlet and pressure outlet (P=0). The flow solver is "cfdemSolverPiso" provided within CFDEMCoupling, and its modified version for nonspherical particles, which is again included within the above-mentioned package, provided by DCS Computing GmbH. ### Contents OpenFOAM and Aspherix simulation data are included in folders "CFD" and "DEM", respectively. * CFD data is in the type of OpenFOAM format, which is well-known in the community. Its visualisation can be done on Paraview using the "controlDict.foam" file in CFD/system subfolder. * DEM/post subfolder includes the simulation data output in vtk format. Further postprocessing can also be done by converting these vtk files to desired format. * DEM/result.txt includes "(simulation time) (total number of particles) (total mass) (total translational specific energy) (total rotational specific energy)" in each row.
