Deep bed filtration with multiple pore-blocking mechanisms

Deep Bed Filtration: Modelling Theory and Practice

Effect of Filter Inhomogeneity on Deep-Bed Filtration Process – A CFD Investigation

Aerosol filtration in fibrous filters is one of the principal methods of removal of solid particles from the gas stream. The classical theory of depth filtration is based on the assumption of existing single fiber efficiency, which may be used to the recalculation of the overall efficiency of the entire filter. There are several reasons for inappropriate estimation of the single fi...

Deep Sequencing of Pyrethroid-Resistant Bed Bugs Reveals Multiple Mechanisms of Resistance within a Single Population

A frightening resurgence of bed bug infestations has occurred over the last 10 years in the U.S. and current chemical methods have been inadequate for controlling this pest due to widespread insecticide resistance. Little is known about the mechanisms of resistance present in U.S. bed bug populations, making it extremely difficult to develop intelligent strategies for their control. We have ide...

A Network Model for Deep Bed Filtration of Solid Particles and Emulsion Drops

A network model has been developed to simulate the flow of emulsions and solid particles through porous media. Particle deposition due to direct interception, as well pore plugging by straining are accounted for in the model. The effects of two important factors-the ratio of particle size to pore size, and the fluid velocity-on particle deposition are also investigated. The strength of the mode...

Deep Bed Filtration Modelling of Formation Damage Due to Particulate Invasion from Drilling Fluids

A Deep Bed Filtration model has been developed to quantify the effect of solids invasion from drilling fluids on the permeability of rock formations. The calculated particletrapping profiles are compared directly with experimental profiles from scanning electron microscopy and synchrotron X -ray diffraction tomography mapping. The computed permeability reduction as a consequence of particle inv...
