A mixing conduit for use within an exhaust treatment system of a work vehicle. The mixing conduit is configured to receive engine exhaust and a mixture of engine exhaust and reductant. The mixing conduit includes an outer tube and an inner tube within the outer tube. Each tube extends lengthwise from upstream ends to downstream ends of the inner and outer tubes, respectively. The inner tube includes an exterior surface, and the outer tube includes an interior surface. The inner tube defines an inner flowpath within the inner tube. The outer tube and inner tube also define an outer flowpath radially between the exterior surface of the inner tube and the interior surface of the outer tube. The mixing conduit further includes one or more swirler vanes extending radially between the exterior surface of the inner tube and the interior surface of the outer tube and within the outer flowpath.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

An exhaust system assembly including a catalyst housing, a catalyst core, and a swirler tube positioned inside the catalyst housing. The swirler tube has a plurality of openings that permit radial exhaust flow into an inner volume of the swirler tube from the catalyst housing. One end of the swirler tube has blades that extend inward and include oblique surfaces arranged at oblique angles relative to a centerline axis of the swirler tube. These blades induce a vortex in the exhaust gases exiting the first swirler tube end. The swirler tube is arranged inside the catalyst housing such that a sequential flow path is created where the exhaust gases flowing through the catalyst housing must first pass through the openings in the swirler tube and then by the blades at the first swirler tube end.

A mixing segment for a static mixer has one inlet section, one outlet section disposed opposite of the inlet section, and a longitudinal axis being defined between the inlet section and the outlet section. The mixing segment further has a plurality of first passages, each first passage adjoining the inlet section and being arranged radially with respect to the longitudinal axis, and at least one second passage adjoining the outlet section and being arranged radially with respect to the longitudinal axis. Said first passages are in fluid connection the second passage with flow paths being defined between said inlet section, said first passages, said second passage and said outlet section.

A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.

A fuel cell system includes a fuel cell stack, a mixed gas supply passage, and an agitation mixer. The fuel cell stack includes a plurality of fuel cells each including a power generation portion. The fuel cells are stacked. The mixed gas supply passage is configured to communicate with the fuel cell stack. The mixed gas supply passage is configured to supply a mixed gas to the fuel cell stack. The mixed gas is a mixture of a fuel gas and a fuel off-gas that has been discharged from the fuel cell stack. The agitation mixer is provided in the mixed gas supply passage. The agitation mixer is configured to apply a swirling force to the mixed gas. The agitation mixer includes a guide rib configured to guide liquid water contained in the mixed gas to a side opposite to the power generation portion-side.

Disclosed material flow amplifiers have opposing amplifier bodies each with a profile that jointly defines an amplifier body (i.e., “clamshell configuration”). The amplifier body has a flow expander section and a vortex inducer section. A vortex chamber insert is within at least an interior space of the vortex inducer section. 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 laminar flow.

The present disclosure relates to a mixer for mixing pasty components, comprising a mixing case extending along a longitudinal axis and having at least one inlet, preferably two inlets, and an outlet, and comprising at least one mixing element received in the mixing case, which defines a plurality of chambers together with the mixing case, said chambers being arranged successively and/or adjacently along a flow path from the inlets to the outlet. The chambers are defined by transverse walls, each extending perpendicularly to the longitudinal axis, and four side walls that each extend parallel to the longitudinal axis, and adjacent chambers are interconnected by a flow by means of through-openings provided in the side walls, the mixing element comprising two strips forming side walls, which are connected by a web that forms other side walls and is perpendicularly arranged in relation to the strips, a first group of chambers having first through-openings arranged in the web, which extend up to a strip, and a second group of chambers comprising second through-openings positioned at a distance to at least one strip in the web.
