Abstract
Flow in porous media with combustion is simulated using the Lattice Boltzmann method (LBM). The d2q9 model for 2D simulation and d3q15 model for 3D simulation are applied. The porous structure is simplified to insert obstacles with square shape in the 2-D or 3-D duct flow. These obstacles are placed randomly to set the porosity. To change the flow characteristics with any roughness in this model, the different number and size of obstacle are used. Results show that combustion of soot is well simulated in the complex flow pattern.
