Figure 5: Transitions to steady asymmetric flow states in various geometries constructed from microscale cylinders as the Weissenberg number is increased beyond a critical value Wic. (a) Flow past a single cylinder positioned on the flow axis. (b) Velocity fields for flow past side-by-side cylinders with different dimensionless intercylinder gap, G = L1/(L1 + L2), where L1 and L2 are the cylinder-cylinder and cylinder-wall gaps, respectively. (c) Velocity fields for flow past two axially aligned cylinders. (d) Retardation fields for flow through a hexagonal array of cylinders. All cases show the flow from left to right of a shear-thinning viscoelastic WLM solution.
