Fig. 2: Schematic illustration of the instability mechanism for asymmetric flows of shear-thinning elastic fluids around cylinders. Coloured regions are indicative of the FIB measured in experiments, or the principle stress difference obtained from numerical simulations. (a) Symmetric flow at Wi ≲ Wic and (inset) perturbation of symmetric flow due to the onset of elastic instability at Wi = Wic. (b) Situation in the asymmetric flow state where a positive feedback loop (indicated by grey arrowed lines) leads to growth of the instability for Wi > Wic.
