A fibrous filter is one of the most common systems used to separate suspended particles from air. Twoimportant factors (i.e., the pressure drop and capture efficiency) are usually used to evaluate the perfor-mance of this type of filter. This study considers three two-dimensional arrangements of fibers (parallel,staggered, and random) to geometrically model fibrous media. The lattice Boltzmann method is employedto numerically simulate fluid flow through the filter. The Lagrangian form of the equation of motion ofa particle is numerically solved to track the path of each particle in the flow field, where a one-wayinteraction between the fluid and particles is considered. The effects of pertinent parameters such as thefiber arrangement, solid volume fraction, particle-to-fiber diameter ratio, particle-to-fluid density ratio,Reynolds number, Stokes number, and size of the fibrous medium on the pressure drop and capture effi-ciency are studied. The obtained results are compared with existing empirical and theoretical findings and discussed.
