Abstract [en]
We report the decoupled effects of inertial and viscous forces on particle focusing, the stability of particles, and particle trajectories to reach equilibrium position in an extended elasto inertial pressure driven flow, in a circular micro-capillary. We report numerically and experimentally for the first time, the existence of multiple stable equilibrium positions in the EEI regime, which was unobserved for flows previously studied at lower Reynolds number viscoelastic flows.
