Spreading of nanofluids on solids
Darsh T. Wasan,Alex D. Nikolov +1 more
TL;DR: Video microscopy is used to demonstrate both the two-dimensional crystal-like ordering of charged nanometre-sized polystyrene spheres in water, and the enhanced spreading dynamics of a micellar fluid, at the three-phase contact region, which suggest a new mechanism for oily soil removal—detergency.
Journal ArticleDOI
Enhanced Oil Recovery (EOR) Using Nanoparticle Dispersions: Underlying Mechanism and Imbibition Experiments
TL;DR: In this paper, the authors present the results of imbibition tests using a reservoir crude oil and a reservoir brine solution with a high salinity and a suitable nanofluid that displaces crude oil from Berea sandstone (water-wet) and single-glass capillaries.
Journal ArticleDOI
Spreading of nanofluids driven by the structural disjoining pressure gradient.
TL;DR: A parametric study of the spreading phenomena by examining the effects of nanoparticle size, concentration and polydispersity on the displacement of an oil-aqueous interface with the aqueous bulk containing nanoparticles.
Journal ArticleDOI
The wetting and spreading of nanofluids on solids: Role of the structural disjoining pressure
TL;DR: In this article, the authors review the progress made in the wetting and spreading of nanofluids over solid surfaces with an emphasis on the complex interactions between the particles in the nanoparticles and with the solid substrate.
Journal ArticleDOI
Superspreading driven by Marangoni flow
Alex D. Nikolov,Darsh T. Wasan,Anoop Chengara,Kalman Koczo,George A. Policello,István Kolossváry +5 more
TL;DR: It is suggested that the spreading of trisiloxane ethoxylates is controlled by a surface tension gradient, which forms when a drop of surfactant solution is placed on a solid surface, and that the aggregates and vesicles formed in trisiles do not initiate the spreading process and therefore these structures are not a requirement for the superspreading process.
