Viscosity enhancement In non-Newtonian flow of dilute polymer solutions through crystallographic porous media

In many practical flow situations solutions of flexible polymers are found to exhibit a well-known non-Newtonian viscosity enhancement effect. This is likely to be due to extensional components in the flow field, which can cause flexible polymer molecules to stretch and orientate, causing an increase in the extensional viscosity. This viscosity enhancement is important in many industrial applic...

Viscosity enhancement in non-Newtonian flow of dilute aqueous polymer solutions through crystallographic and random porous media

We report results on the flow of dilute aqueous solutions of hydrolysed poly(acrylamide) (HPAA) through beds of spheres packed in simple cubic and body-centred cubic crystallographic arrays. Pressure drop measurements made across the arrays as a function of the flow rate have been used to estimate the specific viscosities of the HPAA solutions as a function of the superficial strain rate. It is...

Molecular orientation in non-Newtonian flow of dilute polymer solutions around spheres

The motion of spheres in non-Newtonian liquids is of widespread and fundamental importance to many complex industrial processes. In the oil, paint, detergent and cosmetic industries, for example, there is the problem of controlling the settling and suspension of particles in non-Newtonian media. Study of the flow around a sphere can also benefit the understanding of complex cyclic flows such as...

Relaxation of dilute polymer solutions following extensional flow 1

The relaxation of dilute polymer solutions following stretch in uniaxial extensional flow is investigated via Brownian dynamic simulations of a flexible freely-draining bead-rod chain. The bead-rod chain simulations are compared to Brownian dynamic simulations of a FENE dumbbell and numerical calculations of a FENE-PM chain. A universal relaxation curve for the stress decay from steady-state is...
