A numerical study has been done to investigate the flow inside porous media (PM). Foam type PM used in the study have been classified into different porosity. The different porosity was due to the fabrication technique which involved the dip coating process. Coating technique is known as a method to increase the performance of PM when used as a medium of combustion. In this study, CFD analysis had been performed with 2D models to observe the flow across the PM. The result shows that the CFD model has the ability to predict the pressure drop caused by different porosities on selected coating materials.
