Shear-thinning viscoelastic (STVE) flows exhibit intriguing phenomena owing to their
complex rheology and the coupling of various forces involved. Here, we present an
understanding of the cross-stream migration of droplets in a confined STVE flow and unravel
the role of a shear-thinning induced lift force (F SM) in their dynamical behavior. We perform
experiments with popular STVE liquids of different molecular weights and concentrations (c)
for Reynolds numbers Re< 1 and Weissenberg numbers Wi= 0.01–7.4. Our results reveal …
