“…In the paper of Kostoglou and Konstandopoulos (2000) the deposit evolution on a cylinder was considered for inertial impaction in the limit of high Stokes number. Other studies which attempt to take into account the change in the flow field due to the particle deposit are restricted due to their considerable use of computing time and resources, see Jung and Tien (1993), Biggs et al (2003), Karadimos and Ocone (2003) and Przekop et al (2003).…”

“…Some papers (Dunnett and Clement, 2006;Dunnett and Clement, 2012) take into account deposit growth, but the approach requires making assumptions of deposit structure. The important advantage in deep bed filtration modeling was introduction of lattice gas automata (Biggs et al, 2003) and lattice-Boltzmann method (Long and Hilpert, 2009), that allows to take into account the geometry of flow change due to deposition of suspended particles. Biggs et al (2003) have studied the deposition of particles in 2D constriction unit cell and random 2D porous medium.…”

Deep bed filtration is an effective method of submicron and micron particle removal from the fluid stream. There is an extensive body of literature regarding particle deposition in filters, often using the classical continuum approach. However, the approach is not convenient for studying the influence of particle deposition on filter performance (filtration efficiency, pressure drop) when nonsteady state boundary conditions have to be introduced. For the purposes of this work the latticeBoltzmann model describes fluid dynamics, while the solid particle motion is modeled by the Brownian dynamics. For aggregates the effect of their structure on displacement is taken into account. The possibility of particles rebound from the surface of collector or reentrainment of deposits to fluid stream is calculated by energy balanced oscillatory model derived from adhesion theory. The results show the evolution of filtration efficiency and pressure drop of filters with different internal structure described by the size of pores. The size of resuspended aggregates and volume distribution of deposits in filter were also analyzed. The model enables prediction of dynamic filter behavior. It can be a very useful tool for designing filter structures which optimize maximum lifetime with the acceptable values of filtration efficiency and pressure drop.

“…There have been numerous studies in various fields of chemical engineering (Sharma and Yortsos, 1987;Biggs et al, 2003), environmental engineering (Mondal and Sleep, 2012), mechanical and civil engineering (Adler et al, 2002). The dispersion process of materials in these channels is crucially difficult to predict quantitatively because it depends on geometric characteristics of channels in addition to fluid and particle properties.…”

Gravitational settling of fine particles in a liquid-filled narrow channel has been studied experimentally and theoretically. Previous studies have shown that the particulate suspension with concentration interface toward gravitational direction behaves as a continuous fluid for high concentration and small particle size, and the gravity-induced instability at the interface enhances the settling motion of particles. The purpose of this study is to investigate how such a concentration interface behaves and how particles settle by gravity in various finite-sized channels. The experimental and theoretical results indicate that the aspect ratio of the channel cross-section is an important parameter for describing the settling behavior of particulate suspension. Moreover, we predict the velocity of the collective settling of particles in channels with arbitrary cross-section.
