Abstract
A micro-fluidic flow device and method. The device includes a conduit having an inlet and an outlet distal from the inlet. The conduit further includes a plurality of constrictions each having a reduction in a cross-sectional area of the conduit in a direction from the inlet to the outlet. The constrictions are arranged in series and the reduction in cross-sectional area at each of the constrictions is sufficient to induce extensional flow in a fluid travelling therethrough, such that the maximum strain rate in the extensional flow region is at least 500 s.
