The invention relates to hydrocarbon pyrolysis, to equipment and materials useful for hydrocarbon pyrolysis, to processes for carrying out hydrocarbon pyrolysis, and to the use of hydrocarbon pyrolysis for. e.g., natural gas upgrading. The pyrolysis can be carried out in a reverse-flow reactor.

A water processing system is provided for processing or conditioning water to be distributed to a downstream function or system. The system includes a water processor with a conditioning element disposed inside a housing between an inlet and outlet of the housing. The conditioning element includes a series of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plates may have different configurations of apertures. Optionally, a mixer injector introduces a gas, in the form of gas bubbles, into the water flow upstream of the water processor. The injector introduces additional gas volume in the form of relatively large bubbles, which are subsequently split into smaller bubbles (including nano-bubbles) in the water processor.

A valvular conduit, preferably a Tesla valvular conduit, in which a plug member is coaxially received within a bore in a sleeve member and in which passageways are defined between the plug member and the sleeve member within interior walls configured to permit mixing of fluid flowing through the passageways in at least one direction, preferably, the relatively free passage of fluid through the passageways upstream but increased the resistance to downstream flow of the fluid through each passageway.

A method for reducing gel in a polymer kneaded compound flowing in a polymer flow duct includes flowing a polymer kneaded compound in a polymer flow duct to a gel reduction mechanism including a gel reduction member having one or more through holes defining a squeezing flow path having a flow path cross-sectional area smaller than the polymer flow duct. The squeeze ratio S1/S2 of the squeezing flow path is 25 to 177.8, where S1 is a flow path cross-sectional area of the polymer flow duct and S2 is a sum total of flow path cross-sectional area of the squeezing flow path, to generate an extensional flow in the kneaded compound.

This disclosure relates to nozzles, in particular bath and shower wands that may be hand held and which generate microbubbles from water saturated with air. The bath and shower wands comprise an elongate body comprising an inlet, an elongate outlet and internal flow constriction that can generate micro bubbles from water passing through the wand.

A vehicle exhaust component assembly includes an inlet module configured to receive engine exhaust gas, a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module, and an injection component defining an injection axis and positioned within the internal cavity. The injection component has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component comprises at least a first curved sheet and a second curved sheet that cooperate with each other to surround the injection axis, wherein the second curved sheet is offset from the first curved sheet by a radial gap to create a swirling gas flow within the injection component to mix with fluid injected via the fluid inlet. An outlet module directs a mixture of engine exhaust gas and fluid to a downstream exhaust component.

To provide a nanobubble generating nozzle that is compact and capable of generating nanobubbles with high efficiency. The problem is solved by a nanobubble generating nozzle and a nanobubble generator comprising this nanobubble generating nozzle. The nanobubble generating nozzle comprises an introduction part for introducing a mixed fluid of a liquid and a gas into an interior thereof, a jetting part for feeding out the mixed fluid containing nanobubbles of the gas, and a nanobubble generating structure part for generating nanobubbles of the gas, between the introduction part and the jetting part. The nanobubble generating structure part comprises a plurality of flow paths having different cross-sectional areas through which the mixed fluid of the liquid and the gas is passed, in an axial direction of the nanobubble generating nozzle.

A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.
