On the Viscosity of Concentrated Suspensions of Charged Colloids
(Planta Piloto de Ingeniería Química, 2005-12)
This work is concerned with the theoretical estimation of the low-shear viscosity of concentrated suspensions of charged-stabilized latex particles. Calculations are based on the assumption that particles interacting through ...
Effect of an excess of polyelectrolyte on viscoelastic properties of suspensions of alumina and zircon mixtures
(Elsevier Science, 2007-07-20)
Aqueous suspensions of alumina and zircon mixtures which are of practical interest in ceramics forming process were stabilized with an ammonium salt of a polycarboxilic acid as a dispersant (an anionic polyelectrolyte). ...
Dielectric dispersion in aqueous colloidal systems
(Elsevier Science London, 2010-06)
In this work we describe the fundamentals of the phenomenon of dielectric dispersion in aqueous colloidal suspensions, as well as the most recent advances on the subject. We begin by establishing the admitted definitions ...
Confined suspension jet and long-range hydrodynamic interactions: A destabilization scenario
(AMER INST PHYSICS, CIRCULATION & FULFILLMENT DIV, 2006-08)
The collective dynamics of a quasi-two-dimensional suspension jet, of non-Brownian particles, confined in a thin cell and driven by gravitational force is studied both numerically and theoretically. We present a theoretical ...
Experimental study of solute dispersion in macroscopic suspension flow
(Elsevier, 2012-11)
We experimentally investigate the influence of suspended neutrally-buoyant particles on the dispersion of a passive solute in pressure-driven axial flow in a constant aperture fracture (parallel plates configuration). A ...
Light transmission measurement of solute dispersion in non-Brownian suspension flow
(EDP Sciences, 2014-01)
We characterize and employ a light transmission technique to measure the dispersivity of a solute in the flow of a neutrally-buoyant non-Brownian spherical particle suspension in a Hele-Shaw cell (parallelplate axial flow). ...
