Equivalence of weak and viscosity solutions in fractional non-homogeneous problems
Mathematische Annalen, 2020We establish the equivalence between the notions of weak and viscosity solutions for non-homogeneous equations whose main operator is the fractional p -Laplacian and the lower order term depends on x , u and $$D_s^p u$$ D s p u , being the last one a ...

Effect of Solutes on the Viscosity of Supercritical Solutions
The Journal of Physical Chemistry B, 2007This study shows that solutes can impart significant structure to supercritical solutions, resulting in unexpectedly high solution viscosity at pressures close to the critical value. The viscosity passes through a minimum as the pressure is increased, and this is accounted for by a solvation of the solutes leading to a decrease in solute-solute ...

The viscosity of short polyelectrolyte solutions
Soft Matter, 2014We consider the viscosity of solutions of highly charged short polyelectrolytes. Our system is a poly(styrene-maleic acid) copolymer solution (SMA) with various added salt concentrations in dilute and semidilute regimes. The SMA solutions show some particular features: (i) variations of the specific viscosity measured for different values of ...

Viscosity of polymer solutions
Polymer Science U.S.S.R., 1979Abstract A molecular interpretation was proposed for the dependence of the viscosity of polymer solutions on molecular weight at different temperatures and concentrations. It was shown that a variation in this dependence with certain “intermediate” molecular weights is due to the formation of typical structures in polymer solutions.

The solution viscosity of polybenzyls
European Polymer Journal, 1970Abstract The viscosities of solutions of polybenzyls have been studied according to the view that polybenzyl molecules are highly branched and roughly spherical in shape. A relation between molecular weight and solution viscosity is suggested for these and similar polymers, based on Happel's theory of the viscosity of suspensions of rigid spheres.

The large extensional viscosity of dilute polymer solutions has been shown to dramatically delay the breakup of jets into drops. For low shear viscosity solutions, the jet breakup is initially governed by a balance of inertial and capillary stresses ...
