[HTML][HTML] Shear-thinning and shear-thickening emulsions in shear flows

ME Rosti, S Takagi - Physics of Fluids, 2021 - pubs.aip.org
We study the rheology of a two-fluid emulsion in semiconcentrated conditions; the solute is
Newtonian while the solvent is an inelastic power-law fluid. The problem at hand is tackled …

Emergent cell-free layer asymmetry and biased haematocrit partition in a biomimetic vascular network of successive bifurcations

Q Zhou, J Fidalgo, MO Bernabeu, MSN Oliveira… - Soft Matter, 2021 - pubs.rsc.org
