| Dataset abstract | 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/. |
