Patent ID: 8114319

Claim:
A device for producing a spherical segmented flow of fluid, which device includes: a functional fluid conduit arranged to contain a functional fluid; at least two carrier fluid conduits, each carrier fluid conduit arranged to carry a carrier fluid, the functional fluid conduit merging with the carrier fluid conduits at a junction to form an encased flow conduit thereby permitting functional fluid to be sandwiched (or encased) by the carrier fluid to form an encased flow, the encased flow conduit having a discontinuity therein such that the encased flow forms into a flow of alternate segmented spheres after the discontinuity, wherein the device is provided with a segmented flow conduit downstream of the encased flow conduit, the segmented flow conduit being provided with an enlargement in cross-section and a step coincident with the enlargement in cross-section the depth of the segmented flow conduit immediately downstream of the step being defined as 2a, and the step being provided at a distance of up to 5a downstream of the discontinuity.
