MFIX is a general-purpose hydrodynamic model that describes chemical reactions and heat transfer in dense or dilute fluid-solids flows, flows typically occurring in energy conversion and chemical processing reactors. With such information, the engineer can visualize the conditions in the reactor, conduct parametric studies and what-if experiments, and, thereby, assist in the design process. MFIX has the following modeling capabilities: mass and momentum balance equations for gas and multiple solids phases; a gas phase and two solids phase energy equation; an arbitrary number of species balance equations for each of the phases; granular stress equations based on kinetic theory and frictional flow theory; a user-defined chemistry subroutine; three-dimensional Cartesin or cylindrical coordinate systems; nonuniform mesh size; impermeable and semi-permeable internal surfaces; user-friendly input data file; multiple, single-precision, binary direct-access output files that minimize disk storage and accelerate data retrieval; extensive error reporting; post-processors for creating animations and for extracting and manipulating output data.
