MFiX
MFiX, or Multiphase Flow with Interphase eXchanges, is an open source multiphase flow solver and NETL’s flagship suite of computational fluid dynamics tool for modeling reacting multiphase flows. It has become a standard for comparing, implementing, and evaluating multiphase flow constitutive models, and has been applied to a diverse range of multiphase flow devices and industrial systems. MFiX provides multiple modeling approaches, including a Two-Fluid Model, Discrete Element Model, Coarse-Grained Particle DEM, Superquadric Particle DEM, Glued-Sphere Particle DEM, Particle-in-Cell model, hybrid methods, and a single-phase solver for pure granular flows. These models can be used to simulate gasifiers, circulating fluidized bed combustors, fluidized beds, fluid catalytic crackers, chemical looping combustion systems, and other particle-fluid systems involving hydrodynamics, heat transfer, species transport, and chemical reactions.
