Abstract

Climate change and its consequences make it necessary for human activities to undergo a decarbonization process. Given this scenario, biofuels present themselves as a good alternative as they cause fewer carbon dioxide emissions compared to fossil fuels. This potential for reducing emissions with the adoption of biofuels can be even greater through the adoption of particulate filters that are more efficient in filtering combustion emissions. Therefore, the objective of this work is to study different geometries of porous channels of this type of filter and identify which geometric factors make these filters more efficient, contributing to a better understanding of this phenomenon. The porous channels were simulated with a Python code written by the author specifically for this work. This code used the current-vorticity formulation applied in the finite element method and the parameters analyzed were flow speed, vorticity and current function. From the results obtained, it was observed that the size and distribution of the obstacles that represent the porous medium within the channel are factors that influence the filtration efficiency
