title = "Origins of reduction in efficiency in microfluidic particle separation",
abstract = "Microfluidic particle separation often gets degraded by defocusing of particles at high concentration due to hydrodynamic particle-particle interactions. We theoretically and experimentally studied the origins of these interactions; the reversing wake reflected from nearby channel walls is found to be the dominant interaction. In addition we present a unique mechanism for the dynamic self-assembly particles in finite-Reynolds number channel flow. Inertial lift forces and a parabolic flow field act together to stabilize interparticle spacings that otherwise would diverge to infinity due to viscous wakes.",
