Shear-induced migration of 2 μm diameter spherical colloidal particles flowing through rectangular channels (50 μm × 500 μm cross-section) is studied by confocal microscopy. The confocal microscope allows imaging of the flowing particles far from the walls of the channel, at particle velocities up to 8000 μms−1. The particle volume fraction is varied from φ = 0.05 to 0.34, and the flow rate is also varied, which results in a bulk Péclet number (PeB) which varies by two orders of magnitude… CONTINUE READING
