MFIX input and output files for the study of granular rheology using mixtures with varying size, density, particle friction, and flow geometry
MFIX (Multiphase Flow with Interphase eXchanges) simulation input files and raw particle output files. The study was published in Breard, E. C., Fullard, L., & Dufek, J. (2024). Rheology of granular mixtures with varying size, density, particle friction, and flow geometry. Physical Review Fluids, 9(5), 054303. Description of files 1. Input particle input file (*.dat) 2. VELOCITY* and FORCES* files exported at 10 Hz The simulation are all done as pressure-controlled shear cells where the x and z axes are periodic boundaries, and the top and bottom boundaries are solid rough plates. The simulations are split in three types: MONODISPERSE, BIDISPERSE and TRIDISPERSE, where particle size (in mm), is indicated in the naming of the directory. The, in each set of simulation, the naming is with the following structure: 20N_0.0001ms, where the first number indicates the confining pressure (20 Newtons) and the second indicate the top plate moving velocity in the x-direction (0.0001 m/s). Note the simulations were run with MFIX-18. The MFIX code that is modified from the core code from the Department of Energy (DOE) is all present. The missing core code can be downloaded from the DOE department https://mfix.netl.doe.gov/.

- Statement
- We use the discrete element method to study rheology of dense granular media, taking into account a range of particle size, density, and frictional properties that spans quasistatic to inertial regimes. We find that the stress ratio, , and concentration, , are functions of the inertial number when volume averaging over the contributions of each solid phase is used to compute the mean particle density, friction, and size. In addition, critical packing fraction is linked with distribution skewness and polydispersity, particle friction independent of size distribution. Guided by Kim and Kamrin, Phys. Rev. Lett. 125, 088002, 2020, we put forward a rheological scaling power-law by which all our monodisperse and polydisperse data is collapsed, which relies on dimensionless granular temperature, concentration, and inertial number. The model represents an excellent combination of ()-rheology with kinetic theory, thus enabling the unification of all local and non-local rheology data on one single master curve.
