There is disclosed an arrangement for separating an air-oil mixture in an oil distribution system of an engine. The arrangement comprises a distribution channel of the system, which defines a fluid flowpath suitable for receiving the air-oil mixture, and an ultrasonic transducer configured to insonate the fluid flowpath.

The invention relates to a method for degassing a fluid comprising the following steps: supplying, at the inlet of a reactor comprising at least one microfluidic conduit, a fluid which can comprise at least one dissolved gas; then causing the fluid to flow through the reactor, the at least one conduit comprising a portion having a reduced hydraulic diameter, and the flow being set such that bubbles are generated by micro-cavitation, the fluid then comprising a liquid phase and a gas phase, then allowing the at least partial transfer of the at least one dissolved gas present in the fluid of the liquid phase to the gas phase; separating the liquid phase and the gas phase; and recovering the liquid phase to obtain the degassed fluid, the method not involving the application of ultrasound to the fluid between the step in which the fluid is supplied to the reactor and the step of separating the liquid phase and the gas phase.

Disclosed herein a method of producing an ultrasound that includes defining a set of criteria for an ultrasound emitter comprising a plate. The set of criteria includes a power output criterion, a frequency criterion and number of nodes for a resonance mode of the plate, a focus criterion, and a durability criterion. The method includes determining an outline and a thickness range for the plate, based on the set of criteria. The method includes using topology optimization to determine internodal zone dimensions for the plate, based on the set of criteria, the outline, and the thickness range. The method includes manufacturing the plate according to the internodal zone dimensions.

A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

A method and system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.

Provided are degasification devices and methods of degasifying a liquid. Methods of degasifying a liquid can include filling a liquid chamber with a liquid; increasing an internal volume of the liquid chamber to generate a vacuum within the liquid chamber; applying one or more pressure waves to the liquid in the liquid chamber to accelerate the formation of a plurality of gas bubbles which rise to the surface of the liquid and release gas within the plurality of gas bubbles into a space above the liquid in the liquid chamber; and decreasing the internal volume of the liquid chamber to force the gas through a vapor outlet of the liquid chamber, wherein a degassed liquid remains in the liquid chamber.

A method and system for separating multicomponent fluids into components having different buoyancies. A flow shaping member has a helical channel that imparts a helical motion to the fluid, and a separation chamber for separating the moving fluid into a helically moving heavier flow portion and a more buoyant portion along the central axis. A flow receiving member has a first collection horn with a mouth arranged to collect the higher buoyancy fluid and direct the fluid to an outlet. At least one other fluid passageway for carrying lower buoyancy fluid has an inlet surrounding of the collection horn, and directs the fluid to a separate outlet at an end of the separator. Additional collection horns can be arranged concentrically around the first collection horn to collect intermediate buoyancy flows. Cascaded fluid separators can concentrate the higher buoyancy fluid or the denser fluid.

Disclosed is a degassing apparatus. The degassing apparatus includes a dissolved gas extracting nozzle that extracts dissolved gases in a form of bubbles from a treatment solution including the dissolved gases, a first tank that separates the bubbles extracted while passing through the dissolved gas extracting nozzle from the treatment solution, and a second tank having a stabilization space, in which the treatment solution, from which the bubbles have been separated, is stored from the first tank and is stabilized. The dissolved gas extracting nozzle is configured such that a diameter of an outlet is smaller than a diameter of an intermediate passage such that the dissolved gases in the treatment solution are extracted in the form of the bubbles through a cavitation phenomenon.

A system and method are provided in at least one embodiment to process water to produce gas that can be separated into at least two gas flows using a water treatment system having a disk-pack rotating in it to cause out gassing from the water. In a further embodiment, the method and system use the gas released from the water to produce substantially fresh water from the processed salt water.
