Abstract

In this work the flow behaviour of aqueous sodium montmorillonite dispersions (0.1 – 4.0 vol%) was investigated in a parallel plate geometry with a rheometer. During the rheometer measurements, true velocity profiles in the whole gap (1000 μm) were determined with Optical Coherence Tomography (OCT), which revealed that wall slip and deviations from laminar flow gave rise to artefacts in the flow profiles measured with the rheometer.
