Pipe flow of a dense emulsion: Homogeneous shear‐thinning or shear‐induced migration?
AIChE Journal, 2017Co-Authors: Micheline Abbas, Amélie Pouplin, Olivier Masbernat, Alain Liné, Sandrine DecarreAbstract:The flow field of a 70% concentrated noncolloidal o/w emulsion in a pipe has been investigated by means of Particle Image Velocimetry in a matched refractive index medium. At steady state and in laminar regime, the shape of axial velocity profiles is not parabolic and exhibits a shear‐thinning behavior of the dense emulsion, with a flow index of 0.5 and a negligible yield stress (less than 1 Pa). However, instead of a square root law, the pressure drop increases linearly with Um. To explain this apparent inConsistency, two mechanisms of different nature are considered. The first originates from a possible relation between the Consistency Factor and the drop mean diameter. The second mechanism is shear‐induced migration and leads to the development of a concentration gradient in the pipe cross section. Both mechanisms considered reconcile the experimental data, the apparent local shear‐thinning behavior and the linear evolution of the pressure drop with the flow rate.
