Figure 4.

Demonstration of particle separation. The mixed particle suspension flowed and particle distributions were observed near the outlet for particle mixture of (a) 26 and 15 μm and (b) 26 and 10 μm. Fluorescent streak images on the left and the stacked high-speed images (200 images) on the right. The inertial focusing and the separation distance can be controlled with the flow rate and the radius of curvature; (c) Separation principle based on force balance between inertial lift forces and Dean drag force.
