Abstract: In this work, we report particle focusing at dynamic range of flow rates and particle migration and separation using single inlet high aspect ratio straight microchannels.Our experimental work covers a wide range of dimensionless numbers (0.05 < Reynolds number < 85, 1.5 < Weissenberg number < 3800, 5 < Elasticity number < 470) and our results show that particle size plays a dominant role, and by tuning the parameters, particle focusing can be achieved at Reynolds number ranging from 0.2 -85.As a proof of principle, we demonstrate separation of 5 µm, 7 µm and 10 µm particles in a sheath-less flow at a throughput of 150 µL/min.The presented work sheds light on the complex particle transport in elasto-inertial flows for applications in high-throughput and high-resolution particle separation.
