▪ Abstract Microstructure in an immiscible polymer blend consists of the size, shape, and
orientation of the phases. Blends exhibit many interesting behaviors, including enhanced …

Dilute polymer blends and immiscible liquid emulsions are characterized by a globular
morphology. The dynamics of a single drop subjected to an imposed flow field has been …

The complex rheological behaviour of suspensions is very strongly affected by the details of
the microstructure and the interparticle forces by which it is controlled. The difficulties …

We present a review of some key developments in the continuum mechanics–based
macroscopic modeling of complex fluid flows, following the pioneering work of Oldroyd in the …

We review the concepts of the theory of coarse-graining and its mathematical background
based on the projection operator technique. The objective of the theory is to derive the …

An ellipsoidal model for droplet deformation in mixtures of Newtonian fluids is proposed. The
model makes a bridge between the phenomenological description of the ellipsoidal …

We report a phenomenological constitutive model with no adjustable parameters
appropriate for the transient behavior of droplets and blends. The time evolution of the …

Calculations based on the Grmela et al. model [M. Grmela, M. Bousmina, and JF Palierne,
Rheol. Acta 40, 560 (2001)] for the simple case of ellipsoidal droplet-type morphology …

During crude oil extraction, crude oil is often mixed with water, leading to the formation of
water-in-oil emulsions. Since these emulsions pose severe flow resistance, such as higher …

We propose a family of new models making a direct link between flow and structure for
immiscible mixtures of viscoelastic fluids undergoing high deformation flows. The …
