Abstract
A micromixer device has at least one fluid inlet channel and at least one fluid outlet channel. A plurality of pathways extend between the fluid inlet channel and the fluid outlet channel. The width of at least some of the plurality of pathways varies in a substantially parabolic manner along at least one dimension of the micromixer device.
Claims20
A micromixer device, comprising:
- at least one fluid inlet channel and at least one fluid outlet channel;
- and
- a plurality of pathways between the at least one fluid inlet channel and the at least one fluid outlet channel, a width of at least some of the plurality of pathways varying in a substantially parabolic manner along at least one dimension of the micromixer device.
A microchannel array, comprising:
- a plurality of laminae, at least some laminae comprising at least one micromixer device,
- each micromixer device comprising a plurality of fluid flow pathways between an inlet region and an outlet region,
- wherein the inlet region of the micromixer device is located substantially along a central longitudinal axis of the micromixer device, and the fluid flow pathways vary in length and width relative to their distance from the central longitudinal axis.
A microchannel mixer, comprising:
- a first fluid inlet for introducing a first fluid into the mixer;
- a second fluid inlet for introducing a second fluid into the mixer;
- a serpentine fluid flow pathway;
- a first pump device configured to introduce the first fluid into the fluid flow pathway;
- and
- a second pump device configured to introduce the second fluid into the fluid flow pathway,
- wherein the first and second pump devices are configured to pump the first and second fluids, respectively, into the fluid flow pathway using reverse oscillatory flow.
