  2. In this work, full 3-D numerical simulations are performed to study the combined effects of elastic and inertial forces along the Y and Z-midline of the channel. Ultimately, simulation results are compared and matched with experimental fluorescent streak images of the focusing of particles under the same parametric conditions. We reported that shear-gradient (FSG), N2-induced secondary flow transversal drag (FSF), and elastic (FEL) lift are the main forces responsible for the focusing of particles in the elasto-inertial regime.
