MFIX is a general-purpose computer code developed at the National Energy Technology Laboratory, NETL, for describing the hydrodynamics, heat transfer, and chemical reactions in fluid-solid systems. It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.
