Disclosed is an ultrasonically-enhanced continuous and large-scale production method for nano-formulations. Specifically disclosed is a preparation system for continuous production of nano-formulations, comprising (a) a first pipe, (b) a second pipe, (f) an ultrasonic device, (c) a combined pipe and (e) a (fluid) outlet thereof. The first pipe and the second pipe are connected to the combined pipe. A first phase solution enters the combined pipe through a first pipe outlet, and a second phase solution enters the combined pipe through a second pipe outlet. The ultrasonic device acts on the part or the whole of the combined pipe. The first phase solution and the second phase solution are turbulently mixed in the combined pipe to form a combined phase, and flow out through the outlet of the combined pipe.

An exhaust gas aftertreatment device for a combustion engine includes an exhaust gas guide element that includes a dosage device for introducing a reduction agent into the guide element at a feed point and at least one interference element arranged upstream of the feed point, that introduces turbulences into the exhaust gas flow that is intermixed with the reduction agent. The guide element also includes a first guide portion, through which exhaust gas flows in a first flow direction, and a second guide portion, through which exhaust gas flows in a second flow direction that is opposite to the first flow direction. The first and second guide portions are fluidically connected with each other via a third guide portion, which redirects the exhaust gas from the first flow direction into the second flow direction. The feed point and the interference element are arranged in the third guide portion.

A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.

A mixing device for an exhaust gas conduit comprises a first, inner sleeve having an upstream end, a downstream end and an inner passage extending therethrough having a diameter D. A deflector fin is formed in the first, inner sleeve and extends into the inner passage. A second, outer air-gap shell has an upstream end, a downstream end and a central portion having a diameter D1 that is larger than the diameter D of the first, inner sleeve. The inner sleeve is disposed in the second, outer air-gap shell and the upstream and downstream ends are sealingly fixed to the first, inner sleeve to define an air-gap about the portion of the first, inner sleeve in which the deflector fin is formed.

A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.

A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes, for example, a mixer, a foam injector, and a canister for mixing and moving a slurry mixture of foam and gypsum slurry. Also included in the system is an apparatus having a funnel body constructed and arranged to further mix the slurry mixture. The funnel body includes a number of baffles projecting from its inner wall towards a center and that are spaced around the inner wall. The baffles induce turbulence into the slurry mixture as the slurry mixture moves towards its outlet, thus further mixing the mixture and reducing the flow rate of the slurry mixture before its exits from the outlet for forming the gypsum board.

The present disclosure provides a static mixer for mixing two or more fluids together. The static mixer comprises a tubular body defining a mixing chamber in which spheroidal bodies are positioned. The spheroidal bodies are arranged sequentially within the mixing chamber, and their size and shape is selected so that they maintain a staggered formation. The tubular body can receive a flow of the two or more fluids at one end and convey them towards an opposite end where a mixed product can be provided. The arrangement of the spheroidal bodies can induce turbulence in the flow of the two or more fluids to mix them as they meander around the spheroidal bodies. The present disclosure further provides a method for mixing two or more fluids by the static mixer.

There is provided an oxygenation assembly and an aquaculture diffuser thereof. The diffuser includes a plurality of circumferentially spaced-apart gas injection ports. The diffuser includes a plurality of circumferentially spaced-apart and axially-extending passageways. Each axially-extending passageway aligns with a respective one of the gas injection ports. Each axially-extending passageway is shaped to receive a mixture of water and oxygen-containing gas therethrough. The diffuser includes a plurality of circumferentially spaced-apart and radially outwardly-extending passageways. Each radially-extending passageway is in fluid communication with a respective one of the axially-extending passageways. Each said passageway may include an intensifier or constriction between proximal and distal end portions thereof. The diffuser may include a plurality of circumferentially spaced-apart expansion chambers each positioned between and in fluid communication with a respective said axially-extending passageway and a corresponding respective said radially-extending passageway. The diffuser is shaped to induce a homogeneous ramping turbulent kinetic energy (TKE) dissipation field.

An exhaust hydrogen dilution device includes a purge receiving chamber to store hydrogen purged from a fuel cell of a fuel cell system and an air passage chamber adjoining the purge receiving chamber. Diluter gas flows through the air passage chamber. An interface member between the chambers comprises an interface member having first and second vents respectively on an upstream side and a downstream side. A pressure loss at the first vent is greater than or equal to a pressure loss at the second vent. Some of the diluter gas flows into the purge receiving chamber through the first vent and is mixed with the hydrogen into a mixed gas that flows toward the second vent. The pressure losses are adjusted such that a ratio of the hydrogen flowing into the air passage chamber to a total amount of gases flowing through the air passage chamber is 4% or lower.
