An exhaust gas recirculation ejector system for an engine that includes an air conduit coupled to an engine providing charge air to the engine. The air conduit includes at least one bend formed therein. The at least one bend includes a port formed therein. An EGR conduit is coupled to an exhaust manifold of the engine at a first end of the EGR conduit.

A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

The mixing tee has at least two solvent input ports and a solvent output port in fluid communication with one another. The centrifugal mixing path has a mixing path inlet in fluid communication with the solvent output port of the mixing tee. The centrifugal mixing path includes at least one coiled segment between the mixing path inlet and a mixing path outlet. The low frequency blending mixer is in fluid communication with the outlet of the centrifugal mixing path.

An emulsion system is provided. The system includes a shaft that supports a plurality of cutting assemblies and plates in alternating order, wherein the cutting assembly rotates with respect to an in close proximity to the plate. The plurality of cutting plates each on their circumferential edge have an identification system to memorialize the diameter of the emulsion holes.

A high pressure homogenizer for flowable substances charged with particles, having a high pressure chamber and a homogenizer unit that is located fluidically downstream thereof and, by swirling, expands the fluid to be homogenized which has previously been brought to a pressure of more than 500 bar in the high pressure chamber, and a plunger pump associated with the homogenizer unit, the plunger of which plunger pump pressurizes the high pressure chamber, wherein the high pressure homogenizer has a low pressure chamber which surrounds the plunger shaft to cool the plunger and which has an operating pressure of P.sub.N≤25 bar, wherein the low pressure chamber and the high pressure chamber are separated from each other by a seal which is penetrated by the plunger, the seal being a throttle gap which is formed between the plunger shaft and a bushing that does not contact the plunger shaft, the ratio S/.sub.L of the length to the radial annular gap height of the throttle gap being ≤0.0015.

A microfluidic mixing device (101) comprising: a mixing chamber; one inlet channel (104) into the mixing chamber (102) for a first fluid and two inlet channels (103a, 103b) into the mixing chamber for a second fluid, said inlet channels being disposed substantially symmetrically at a proximal end (108) of the mixing chamber; at least one outlet (105) for mixed material at a distal end of the mixing chamber, wherein the mixing chamber comprises one or more baffles.

The present technology relates to an efficient process of mixing, dispersing and integrating reduced graphene oxide (RGO) or carbon nanomaterials or nanostructured materials to the epoxy matrix of the “fusion-bonded epoxy” (FBE) type. The polymeric material consists of a mixture of the solid epoxy particulate with a curing agent, catalyst, pigments and inorganic additives. It allows to integrate nanometric particulate additives in FBE, using FBE in solid state. Powder FBE+RGO system mixes are produced by means of a planetary ball mill or high energy planetary ball mill with internal addition of balls, with time and rotation control. The mixtures show little or no sign of RGO aggregation after application of the composite as a coating on metals. The mixture of FBE+RGO can be applied to metallic surfaces to protect against abrasive processes and corrosion without compromising the properties presented by FBE applied without nanomaterials. There were increases of up to 11% in abrasion resistance, improvement in the material's resistance to accelerated tests, such as immersion in a hot water bath, and a significant increase in adherence, of approximately 100% after the hot bath immersion test.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

The systems and methods disclosed herein provide for the efficient generation of fine bubbles.
