  • Patent number: 10684201
    Abstract: Fluidic devices and methods associated with mixing of fluids in fluidic devices are provided. In some embodiments, a method may involve the mixing of two or more fluids in a channel segment of a fluidic device. The fluids may be in the form of, for example, at least first, second and third fluid plugs, composed of first, second, and third fluids, respectively. The second fluid may be immiscible with the first and third fluids. In certain embodiments, the fluid plugs may be flowed in series in the channel segment, e.g., in linear order, causing the first and third fluids to mix without the use of active components such as mixers. The mixing of fluids in a channel segment as described herein may allow for improved performance and simplification in the design and operations of fluidic devices that rely on mixing of fluids.

A plurality of vane members are also supported within the mixing section to promote fluid mixing. When used in an open channel, the static mixer having at least one conical section has a lower head loss in a shorter distance downstream from the mixing device than other conventional static mixers. In addition, the mixer is self-contained and is easy to mount, lightweight, and less expensive to manufacture and maintain than conventional open channel mixers.

  • Patent number: 8967852
    Abstract: A mixer for mixing immiscible fluids includes a mixer housing defining a flow passage therethrough from a first fluid inlet to an outlet thereof. An upstream portion of the flow passage defines a main longitudinal axis. A second fluid inlet is provided downstream of the first fluid inlet in fluid communication with the upstream portion of the flow passage. The second fluid inlet is offset with respect to the main longitudinal axis of the flow passage to introduce fluid along a path that is offset with respect to the main longitudinal axis for inducing swirl on fluids introduced at the first and second fluid inlets. In certain embodiments, a mixer section is included having a flow constriction defined in a downstream portion of the flow passage with a flow area smaller than that of the upstream portion of the flow passage for enhancing turbulent mixing of fluids therein.

    Abstract: The present invention relates to a mixer device for distributing and evaporating a liquid introduced into a gas flow, in particular into an exhaust-gas flow, wherein the mixer device comprises at least one mixer vane (14a) which influences the flow direction of the gas flow. The mixer vane has a first vane (14a?) portion and a second vane portion (14a?) which are arranged in series in the flow direction of the gas flow, which vane portions are designed so that the first vane portion diverts the gas flow approaching the mixer device such that said gas flow has a first swirl component imparted thereto, and so that the second vane portion subsequently diverts the gas flow such that said gas flow has a second swirl component imparted thereto, wherein the first swirl component and the second swirl component oppose one another.

  • Publication number: 20140347953
    Abstract: A static fluid and a second fluid are placed into contact along a microfluidic free interface and allowed to mix by diffusion without convective flow across the interface. In accordance with one embodiment of the present invention, the fluids are static and initially positioned on either side of a closed valve structure in a microfluidic channel having a width that is tightly constrained in at least one dimension. The valve is then opened, and no-slip layers at the sides of the microfluidic channel suppress convective mixing between the two fluids along the resulting interface. Applications for microfluidic free interfaces in accordance with embodiments of the present invention include, but are not limited to, protein crystallization studies, protein solubility studies, determination of properties of fluidics systems, and a variety of biological assays such as diffusive immunoassays, substrate turnover assays, and competitive binding assays.

  • Publication number: 20140334251
    Abstract: Mixers in microfluidic separation systems comprise multiple fluidic paths that extend from a distribution well to a mixing well. An incoming flow of solvent composition splits at the distribution well into as many streams as fluidic paths. The streams recombine at the mixing well to produce an output stream. One embodiment has fluidic paths with different dwell volumes that determine a percentage of the incoming flow flowing through each path. These dwell volumes can be targeted to attenuate a known noise characteristic in the incoming compositional flow. Another embodiment of mixer has a contoured surface disposed between the distribution and mixing wells. The paths extend from the distribution well to the mixing well through this contoured surface, each path passing through a different valley defined by opposing upwardly sloping banks. The valleys can have different dwell volumes that determine a percentage of the incoming compositional flow flowing through each valley.
