Effect of viscosities of dispersed and continuous phases in microchannel oil-in-water emulsification [PDF]

, 2010
Although many aspects of microchannel emulsification have been covered in literature, one major uncharted area is the effect of viscosity of both phases on droplet size in the stable droplet generation regime. It is expected that for droplet formation to

Dynamic interfacial tension effects in the rupture of liquid necks [PDF]

Journal of Fluid Mechanics, 2012
AbstractBy examining the rupture of fluid necks during droplet formation of surfactant-laden liquids, we observe deviations from expected behaviour for the pinch-off of such necks. We suggest that these deviations are due to the presence of a dynamic (time-varying) interfacial tension at the minimum neck location and extract this quantity from our ...

Formation of water-in-diesel oil nano-emulsions using high energy method and studying some of their surface active properties

Egyptian Journal of Petroleum, 2011
In this work, formations of water-in-diesel oil nano-emulsions using water/mixed nonionic surfactant/diesel oil system have been studied. The high energy emulsification method was used to form three emulsions using different water contents: 5%, 10% and ...

Dynamic Interfacial Tension Measurements with Microfluidic Y-Junctions

Langmuir, 2009
Emulsification in microdevices (microfluidic emulsification) involves micrometer-sized droplets and fast interface expansion rates. In addition, droplets are formed in less than milliseconds, and therefore traditional tensiometric techniques cannot be used to quantify the actual interfacial tension.

Dynamic interfacial properties of human apolipoproteins A-IV and B-17 at the air/water and oil/water interface

Journal of Lipid Research, 2000
Viscoelastic behavior of proteins at interfaces is a critical determinant of their ability to stabilize emulsions. We therefore used air bubble surfactometry and drop volume tensiometry to examine the dynamic interfacial properties of two plasma ...

Fabrication of New Demulsifiers Employing the Waste Polyethylene Terephthalate and their Demulsification Efficiency for Heavy Crude Oil Emulsions

Molecules, 2021
Two novel amphiphilic polyethylene amine terephthalate have been prepared via the glycolsis of polyethylene terephthalate (PET). The product, bis (2-hydroxyethyl terephthalate) (BHET), was converted to the corresponding dialkyl halide, bis(2-chloroethyl)

Viscosity scaling of fingering instability in finite slices with Korteweg stress

, 2015
We perform linear stability analyses (LSA) and direct numerical simulations (DNS) to investigate the influence of the dynamic viscosity on viscous fingering (VF) instability in miscible slices.

Influence of processing parameters and composition on the effective compatibilization of polypropylene–poly(ethylene terephthalate) blends [PDF]

, 2016
The effects of the addition of different functionalized compatibilizers on toughness, morphology and rheological properties of a polypropylene (PP) - poly(ethylene terephthalate) (PET) (85-15 wt%) blend were studied.
