The wetting behavior of oil on water (or brine) has important consequences for the transport properties of oil in watercontaining porous reservoirs, and consequently for oil recovery. The equilibrium wetting behavior of model oils composed of pure alkanes or alkane mixtures on brine is reviewed in this paper. Intermediate between the partial wetting state, in which oil lenses coexist on water w...

Differential wetting of pristine and ozonized carbon nanotubes has been studied using solvents like acetonitrile and dichloromethane in comparison to the well-known wetting behavior of water. Based on their unique structural and physical properties, functionalized CNT substrates have been used due to the fact that independent variation in molecular as well as electronic properties could be cont...

Within the context of immiscible biphasic flow in porous media, when nonwetting fluid invades pore spaces which are a priori saturated with wetting fluid, capillary forces dominate if network is formed by fine-grained soils. Owing to cohesion-less frictional behavior such soils, force–driven fracturing phenomenon has been put forward some researchers. Unlike purely mechanistic tensile mode-I th...

Internal pipeline corrosion in oil production and transportation is always associated with the presence of water, and the likelihood of corrosion generally increases with the volume fraction of water. When the walls of the pipeline are wetted with oil no corrosion is possible. Highly turbulent flow was associated with negligible corrosion due to water entrainment by the flowing oil, whereas low...

The novella Coraline follows a young girl as she rescues her parents from an alternate reality. In his short story, author Neil Gaiman covers scarcely one week of Coraline’s life. Still, the descriptions of Coraline’s experiences and thoughts can engage Carl Jung’s psychological theories of personality structure and individuation. In particular, I will analyze how Coraline’s character illustrat...

Provisioners capture items both for delivery and for self-feeding. In doing so, they may travel directly to and from a single location, visit several patches on each excursion from a delivery point, or alternate excursions to different destinations. Prey suitable for self-feeding versus delivery have differing attributes, which means that they are often best sought in different places. Visiting...

We use numerical experiments to analyze the kinetics of grain boundary wetting in polycrystalline aggregates under the influence of an external applied shear stress. Grain boundary wetting is driven by the stress concentration at the tip of the fluid front. The extent of wetting of favorably oriented grain boundaries depends on the fluid mobility number b, which is defined as the ratio of the r...

Conventional wetting theories on rough surfaces with Wenzel, Cassie-Baxter, and Penetrate modes suggest the possibility of tuning the contact angle by adjusting the surface texture. Despite decades of intensive study, there are still many experimental results that are not well understood because conventional wetting theory, which assumes an infinite droplet size, has been used to explain measur...
