Electroviscous effect of moderately concentrated colloidal suspensions

Article Abstract:

The electroviscous effect of a colloidal suspension is considered. A new development, based upon a cell model concept that is valid for Newtonian fluids and disordered systems, which imposes the condition of low shear rate, corresponding to the low Newtonian plateau in general flow curves of colloidal suspensions. The numerical results are analyzed, resulting in a dependence of the electroviscous effect with the particle concentration.

Electroviscous effect of moderately concentrated colloidal suspensions under overlapping conditions

Article Abstract:

A theoretical model for the calculation of the electroviscous coefficient of a colloidal suspension is presented. The development used is based on a cell model, which is applicable to Newtonian suspensions under low shear conditions and without crystalline ordering.

Electroviscous effect of moderately concentrated colloidal suspensions: Stern-layer influence

Article Abstract:

The presence of a dynamic Stern layer (DSL) in the immediate vicinity of the colloidal particles is presented. The inclusion of a dynamic Stern layer will be required to match the predictions with the experimental results.
