Abstract
Given that combustion synthesis reactions have a highly exothermic nature and a high activation energy, filtration combustion proceeds in the form of sharp fronts. Various front propagation phenomena are observed due, not only to the non-linear nature of the system, but also to the interaction of the gas-flow with the combustion front. In this study, a two-dimensional model of filtration combustion [1] in FLUENT using user-defined-functions (UDFs) was successfully expanded into a three dimensional model to study the behavior of the real systems. The implementation of the new three-dimensional model is validated using a sample problem solved earlier by Degreve et al. [2] and the new model correctly captures the complex behavior of the combustion front.

Keywords: Filtration combustion, FLUENT user-defined-functions, Three-dimensional.
