The simulation of combustion phenomena poses a real challenge to numerical methods due to the widely disparate time and length scales present in these systems. Several commercial computational fluid dynamics (CFD) codes with "similar" capabilities in the market are powerful, interactive environment for modeling and solving scientific and engineering problems based on partial differential equations. Some of the processes occurring in real world problems cannot be simulated using the standard version of CFD software. In this study, even though not limited in dimensions, a new two-dimensional model of filtration combustion in FLUENT using user-defined-functions (UDFs) are developed to simulate the self-propagating high-temperature synthesis (SHS) of nitrides.
