Material flow amplifiers overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

Disclosed cyclonic flow-inducing pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such cyclonic flow-inducing pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated adverse considerations such as slugging.

A flow-path-regulating, dip-tube device is an adaptable, scalable, flow-through performance enhancement to any vessel-type, reaction containment apparatus. This apparatus is embodied as a reconfigurable, quasi-dip tube which modularly improves reaction processing, performance, and efficiency. This apparatus increases operational flexibility, adaptable design, and vastly improves efficiencies and flow predictability of vessel-type reaction containers by retrofitting them with benefits of tubular reaction-containment configurations. Internally, the dip-tube device defines one or more closely spaced, functional voids which operate as fluid channels that can be configured in various geometric or topologic arrangements. The dip-tube apparatus is widely scalable, provides high thermodynamic efficiency, manufacturing simplicity, and affordability for varied operations through additive manufacturing, and has a compact physical footprint conformally fitted within a parent container.

A biological fluid sample analysis cartridge is provided. The cartridge includes a housing, a fluid module, and an analysis chamber. The fluid module includes a sample acquisition port and an initial channel, and is connected to the housing. The initial channel is sized to draw fluid sample by capillary force, and is in fluid communication with the acquisition port. The initial channel is fixedly positioned relative to the acquisition port such that at least a portion of a fluid sample disposed within the acquisition port will draw into the initial channel. The analysis chamber is connected to the housing, and is in fluid communication with the initial channel.

A two part adhesive packaging system is provided. The packaging system includes two containers for holding a two-part adhesive. The packaging system further includes a connector having two ports for communicating with the containers. A mixing nozzle is attachable to the containers. The mixing nozzle includes a membrane disposed therein. The membrane is configured to break upon application of a sufficient force thereon, such as by pumping or pushing the two-part adhesive from the containers.

Aspects of the present disclosure provide various apparatus and methods. In some embodiments, an apparatus is provided for mixing a gas with a liquid. The apparatus may include a pipe having two ends. The pipe may provide a main fluid path and may have an interior surface having a first groove. The apparatus may also include a helical vane disposed inside the pipe. The vane may have a first projecting tongue that engages the first groove. The apparatus may also include a gas injection port on the pipe adapted to inject gas into the fluid path upstream of the helical vane. In some embodiments, the helical vane may be a 3D printed component.

Methods and systems are provided for an exhaust gas mixer. In one example, a system may comprise an outer annular portion exterior to an exhaust pipe and an inner annular portion interior to the exhaust pipe, where the outer annular portion comprises a spiral fin extending around the exhaust pipe in a downstream direction.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

A fluid mixing device comprises a tubular structure including an inner wall which defines a channel, and a plurality of flow deflection elements which are supported by the structure and located within the channel. Each flow deflection element defines a surface that extends between a first leading edge, which extends transversely around a first portion of the inner wall of the hollow tubular structure, and a first trailing edge which is spaced in a longitudinal direction from the first leading edge and extends radially inwardly from the inner wall. Such a device may be used on a large scale, for example in industrial systems, and also on a smaller scale, such as in microfluidic systems for biological and chemical analysis.
