Flow of wormlike micelles in confined geometry
ORAL
Abstract
We study wormlike micelles flowing in confined geometry to study the local rheology of such fluids. Experiments show that the properties of such fluids undergoing a strong shear stress gradient can only be described by an equation including non-local terms. Then the flow of very long wormlike micelles is studied both in microfluidic channel and in Couette geometry coupling with ultrasonic velocimetry.
