Particle partitioning in a Giesekus fluid. Difference of particle flux ratio minus flow rate ratio as a function of the flow rate ratio for three different confinement ratios: \(\beta =0.1\) (a), \(\beta =0.2\) (b) and \(\beta =0.5\) (c). In each panel, three different \(\Lambda -\)values have been considered. The lines are fits of the simulations data that are added as a guide for eye. In (a) and (b), the solid lines have been obtained by considering the data at \(Q_\text {IN}=1/3\) and \(Q_\text {IN}=2/3\), whereas the dashed lines refer to the data at \(Q_\text {IN}=4/3\).
