Microstructural evolution in polymer blends

CL Tucker III, P Moldenaers - Annual Review of Fluid Mechanics, 2002 - annualreviews.org
▪ Abstract Microstructure in an immiscible polymer blend consists of the size, shape, and
orientation of the phases. Blends exhibit many interesting behaviors, including enhanced …

Emulsion drops in external flow fields—the role of liquid interfaces

P Fischer, P Erni - Current Opinion in Colloid & Interface Science, 2007 - Elsevier
We review the flow of emulsion drops, focusing on recent work involving complex interfaces,
which may include the presence of surfactants, particles, surface-active polymers, or solid …

Equation of change for ellipsoidal drops in viscous flow

PL Maffettone, M Minale - Journal of Non-Newtonian Fluid Mechanics, 1998 - Elsevier
A simple phenomenological model for the deformation of a droplet immersed in a fluid
subjected to a flow field with a uniform, but otherwise arbitrary, velocity gradient is …

Drop deformation in microconfined shear flow

V Sibillo, G Pasquariello, M Simeone, V Cristini… - Physical review …, 2006 - APS
The deformation and breakup of a drop in an immiscible equiviscous liquid undergoing
unbounded shear flow has been extensively investigated in the literature, starting from the …

Drop breakup in three-dimensional viscous flows

V Cristini, J Bławzdziewicz, M Loewenberg - Physics of Fluids, 1998 - pubs.aip.org
A new three-dimensional boundary integral algorithm is presented that is capable of
simulating the process of drop breakup in viscous flows. The surface discretization is fully …

On coherent vortical structures in wave breaking

S Di Giorgio, S Pirozzoli, A Iafrati - Journal of Fluid Mechanics, 2022 - cambridge.org
The flow generated by the breaking of free-surface waves in a periodic domain is simulated
numerically with a gas–liquid Navier–Stokes solver. The solver relies on the volume-of-fluid …

Drop breakup and fragment size distribution in shear flow

V Cristini, S Guido, A Alfani, J Bławzdziewicz… - Journal of …, 2003 - pubs.aip.org
We report a study on the deformation and breakup of drops in an impulsively started shear
flow under Stokes flow conditions using boundary-integral simulations and video …

Bubble shapes and orientations in low Re simple shear flow

AC Rust, M Manga - Journal of colloid and interface science, 2002 - Elsevier
We present measurements of shape and orientation of air bubbles in a viscous Newtonian
fluid deformed by simple shear. The apparatus is a variation of the “parallel band” device …

Rheology and Miscibility of Linear/Hyperbranched Polydimethylsiloxane Blends and an Abnormal Decrease in Their Viscosity

SO Ilyin, VG Kulichikhin - Macromolecules, 2023 - ACS Publications
Linear polymers with the same monomer units and different molecular weights form miscible
blends considered to be single polymers, but the situation changes if one is hyperbranched …

Influence of surface viscosity on droplets in shear flow

J Gounley, G Boedec, M Jaeger… - Journal of Fluid …, 2016 - cambridge.org
The behaviour of a single droplet in an immiscible external fluid, submitted to shear flow is
investigated using numerical simulations. The surface of the droplet is modelled by a …
