MFiX User Manual

MFiX is a multiphase flow solver, providing: a Single-phase solver, a Two-fluid model (TFM), a Discrete element model (DEM), a Coarse-grained particle DEM (CGP), a Superquadric particle DEM (SQP), a Glued-sphere particle DEM (GSP), and a Particle-in-cell (PIC) model

These models can be used to simulate a variety of multiphase flow devices including gasifiers, circulating fluid bed combusters, fluidized beds, fluid catalytic crackers, and chemical looping combustion systems. Please visit the Multiphase Flow Science website for more information.
