| Dataset abstract | MFIX (Multiphase Flow with Interphase eXchanges) simulation input files and raw particle output files. Description of files 1. The directory "MFIX_Setup" contains the MFIX simulation input files for the two simulations Exp19 and Exp35. (MFIX input file (input and boundary conditions) *mfx & MFIX subroutines (*f) and geometry *stl) 2. The directory "time-averaged_slices" contain the time-average slices as *vtu files for Exp19 and Exp35 that can be opened using Paraview (open-source software). 3. The directory "depth-averaged and time-averaged data" contains the python code that reads the depth- and time-averaged data. Note the simulations were run with MFIX-20. The two simulation (Exp19 and Exp35) are 3D two-fluid model (TFM) numerical simulations of liquid-particle mixture, where the fluid and particles are saline water and silica particles, respectively. The finite-volume method is used to solve the mass, momentum and energy equations of the two phases and the solid-fluid coupling is done using drag and pressure terms. 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/. |
