Capillary imbibition of aqueous foams by miscible and nonmiscible liquids.
When put in contact with a large liquid drop, dry foams wick owing to surface-tension-driven flows until reaching equilibrium. This work is devoted to the dynamics of this imbibition process. We consider imbibition of both wetting or nonwetting liquid, by putting the dry foam into contact either with the foaming solution that constitutes the foam or with organic oils. Indeed, with the appropria...
متن کاملImbibition and Flow of Wetting Liquids in Noncircular Capillaries
Micromolding in capillaries (MIMIC) has been used to study the dynamics of imbibition of liquid prepolymers in micrometer-scale, rectangular capillaries formed between an elastomer containing relief structures and a self-assembled monolayer (SAM) of alkanethiolates on gold supported on Si/SiO2. Self-assembled monolayers provide a wide range of solid/vapor interfacial free energies (γSV) and a c...
متن کاملInteractions between Carbon Nanotubes and Liquids: Imbibition and Wetting
We report on our progress to extend the current experimental measurements of interactions between fluid and materials to times and length scales characteristic of nanomaterials. The rapid imbibition of decane and nonpolar fluids by carbon nanotubes is investigated to confirm recent theoretical results obtained using MD simulations. The wetting dynamics of carbon nanotubes and larger carbon fibr...
متن کاملEffect of Nanoparticles on Spontaneous Imbibition of Water into Ultraconfined Reservoir Capillary by Molecular Dynamics Simulation
Imbibition is one of the key phenomena underlying processes such as oil recovery and others. In this paper, the influence of nanoparticles on spontaneous water imbibition into ultraconfined channels is investigated by molecular dynamics simulation. By combining the dynamic process of imbibition, the water contact angle in the capillary and the relationship of displacement (l) and time (t), a co...
متن کاملVolumetric components of seed imbibition.
Swelling parameters were determined for 15 seed species; the swelling quotients were found to range from less than 1.1 (castorbean) to 2.8 (mungbean) and swelling coefficients ranged from 0.09 (castorbean) to 0.42 (cowpea). Swelling leads to a lowering of specific gravity of those seeds with high initial specific gravity, and an elevation of those with low initial specific gravity. The extent o...
