Title: Transport Phenomena of Highly Concentrated Slippery Particles in Confined Fluid Flow
Abstract: Highly concentrated slippery particles display non-trivial behavior in confined microfluidic spaces due to slip at the particle-fluid interface. We hypothesize that increased slip velocity in slippery particles should further amplify the central migration effect displayed by high particle concentrations. In this work, we use fluorescent polyethylene particles to study the transport of highly concentrated particles under varying flow conditions, comparing the effects of slip and non-slip interfaces. Our experimental observations align with our computational results, confirming that slippery particles exhibit significantly greater migration toward the channel centerline.
