Influence of discrete arrangement of porous filters on pressure drop

One of the problems of the modern world is air pollution by harmful substances contained in the exhaust gases of cars. To solve this problem, diesel, and gasoline porous particulate filters are used. However, it is necessary that the porous filter create a minimum pressure drop while maintaining a high filtering capacity. The purpose of the study is to identify the feasibility of a discrete arrangement of filters to reduce the pressure drop. In this work, we carried out a study to determine the pressure drop in porous filters with porosity values ε=0.75 and ε=0.58. Experiments on measuring the pressure drop were carried out for a different number of filters (from 2 to 5), arranged continuously and discretely
