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.
Claims13
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 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 pump system with a first oscillatory flow pump device and a second oscillatory flow pump device, the first oscillatory flow pump device being operative coupled to the first fluid inlet and the second oscillatory flow pump device being operative coupled to the second fluid inlet configured
- wherein the first oscillatory flow pump device and second oscillatory flow pump device pump the first and second fluids, respectively, into the fluid flow pathway using reverse oscillatory flow;
- wherein the first and second oscillatory flow pump devices both comprise two pump members, with each pump device having a first pump member configured for forward sinusoidal flow and a second pump member configured for reverse sinusoidal flow.
