This is a modified version of CFDEM.

Author: Linhan Ge, School of Engineering, the University of Newcastle.

Typical features:

CFD-DEM solver with diffusion averaging method developed by Sun and Xiao

• Grid cells that smaller than particles can be used to resolve the fluid flow.
• Details can be found in the below paper:

Ge, L., Evans, G. M., & Moreno-Atanasio, R. (2020). CFD-DEM investigation of the interaction between a particle swarm and a stationary bubble: Particle-bubble collision efficiency. Powder Technology.

Please cite my paper if you use the solver in your research.

VOF-DEM solver with diffusion averaging method developed by Sun and Xiao

• Gas-liquid-solid three phase flow solver capable of resolving gas-liquid interfaces using extremely fine meshes whilst guaranteeing physical particle dynamics.
• Details can be found in the below paper:

Ge, L., Peng, Z., Moreno-Atanasio, R., Doroodchi, E., & Evans, G. M. (2020). A Three-dimensional VOF-DEM Model for Simulating Particle Dynamics in the Liquid Slugs of a Vertical Gas-Liquid-Solid Taylor Flow Microreactor. Industrial & Engineering Chemistry Research.

Installation procedures:

• Install OpenFOAM 5.x.
• Install the smoothing curvature feature for interFoam developed by Kevin van As.
• Install CFDEM as described in the CFDEM manual but using the CFDEM repository here and LIGGGHTS-LG repository (HPC branch). Noting that the folder name should be changed from CFDEMcoupling-LG to CFDEMcoupling-PUBLIC-5.x.
• Please set up your own cases following the examples in the tutorials.
