Abstract
One possible source of error in rheological characterization of concentrated suspensions using nonhomogeneous flows is the migration of particles from high to low shear rate regions to give rise to concentration gradients in the specimen. Numerical data are presented and simple experimental procedures are suggested for the assessment of the particle-migration effects in pressure-driven viscometers including capillary and rectangular slit viscometers.
