Abstract	Air pollutants are among the hazardous materials for human health. Therefore, many scientists are interested in removing particles from the carrier gas. In this study, flow of air and airborne particles through the virtual multi-fibrous filters that consist of different fiber cross-sectional shapes and arrangements is simulated where particle deposition and filtration performance are studied. Regular and irregular arrangements of fibers with the circular, elliptical, and equilateral triangular cross sections have been considered. Effects of important parameters such as solid volume fraction, internal structure, and filter thickness on particle collection efficiency and pressure drop are investigated, and the best internal structure of the multi-fiber filters for the collection of particles is obtained. Results indicate that an increase in the ratio of the vertical distances between fibers to fiber diameter and the solid volume fraction would result in a dramatic reduction of filtration. Collection efficiency of multi-fiber filters is validated with the available numerical studies.
