Particle Transport Through Porous Media. porous media at typical groundwater flow velocities. As particles accumulate within media pores, available models become less predictive because of the. Examples of industrial porous media and corresponding processes are drying of paper pulp, the adsorption of liquids in diapers and similar absorbing products, gas and water management in fuel cells, and the drying of foods, as well as water and solute movement in building materials, detergent tablets, textiles, foams, coatings, paper, and filters.
Abstract. Lungs are natural porous structures that are unique, challenging, and high-value media to study. There are multiple drivers to obtain an improved understanding of their architecture and function: to increase high-value information and insights that can be applied in healthcare, to devise control strategies that will limit some hazards effects, and to expand boundaries of what is Cited by: Investigation of Nanoparticle Adsorption During Transport in Porous Media Flow in Porous Media, Tracers, Rock properties, Sand/Solids Control, Separation and Treating, Processing Equipment, Coring, Fishing Keywords Adsorption, Porous media, Transport, Nanoparticle Downloads 6 in the last 30 days Cited by: 9.
Experiments with a variety of nanoparticles and porous media yield a wide range of adsorption capacities (from 10 –5 to 10 1 mg/g for nanoparticles and rock, respectively) and also a wide range of proportions of reversible and irreversible adsorption.
