Abstract
The simulations show that, in agreement with the previous literature, a mastercurve relating the migration velocity of the particle to its 'vertical' position completely describes the phenomenon. Remarkably, we found that, for comparable values of the Deborah and Reynolds numbers, inertial effects are negligible: migration is in practice driven by fluid viscoelasticity only. At moderate Reynolds numbers (20
