AB  - Purpose The purpose of this work was to study the influence of particles and fiber material properties on the deposition efficiency. Collection of aerosol particles in the particular steps of their production, and purification of the air at the workplace and the atmospheric environment requires the efficient method of separation of particulate matter from the carrier gas. There are many papers published in the past years in which the deposition of particles on fibrous collectors is considered. Most of them assume that collisions between particles and collector surfaces are 100% effective.Design/methodology/approach For the purpose of this work, the lattice Boltzmann model was used to describe fluid dynamics, whereas the solid particles motion was modeled by the Brownian dynamics. The interactions between particles and surfaces were modeled using an energy-balanced oscillatory model.Findings The results show significant impact of material properties on filter performance.Practical implications Obtained results may provide useful information for the proper design of a filtration process and the production of filters with long service life.Originality/value In addition, the results presented in this work show that some assumptions of the classical filtration theory lead to an overestimation of deposition efficiency.
