Disclosed herein are phase separator devices, and related methods of fabrication and use. The disclosure provides improved phase separator devices for phase separation of input feeds, and systems/methods for utilizing and fabricating the devices. The disclosure provides phase separator devices utilizing inertial separation and porous media extraction for the phase separation of two-phase input feeds (e.g., to separate an input feed of a two-phase mixture to a first phase output (e.g., to a liquid output flow) and to a second phase output (e.g., to a gas output flow)). The device can separate a mixed fluid flow of both liquid and gases. The liquid and gas can include liquid and vapor phases of the same chemical/constituent (e.g., ammonia), or may include liquid and gases of two different constituents (e.g., liquid water and air). The phase separator devices can be utilized at standard gravity to micro-gravity to zero gravity environments.

A turbine engine having an inducer assembly. The inducer assembly includes a centrifugal separator fluidly coupled to an inducer with an inducer inlet and an inducer outlet. The centrifugal separator includes a body, an angular velocity increaser to form a concentrated-particle stream and a reduced-particle stream, a flow splitter, and an exit conduit fluidly coupled to the body to receive the reduced-particle stream and define a separator outlet.

To improve separation performance of oil. An oil separation structure 55 includes a partition member 62 configured to partition the inside of a separation chamber 42 in the up-down direction. The partition member 62 includes a cylindrical support portion 71 supported by an inner circumferential surface 63 of the separation chamber 42 and a cylindrical swirl acceleration portion having an upper end side continuously formed from the support portion 71, having a smaller diameter than the support portion 71, and having a lower end side closed, and the swirl acceleration portion has a communication path 75 formed, the communication path 75 communicating the radial inside and the radial outside with each other, and accelerates swirling of refrigerant, the refrigerant having descended while swirling along the inner circumferential surface 63 of the separation chamber 42.

A vacuum cleaner separation system having: a cyclone tube having a cyclone chamber and an inner wall having a substantially cylindrical appearance defining a center axis; an inlet channel offset with respect to the center axis for receiving dust laden air; a dust outlet for discharging dust from the cyclone tube; an air outlet for discharging air from the cyclone tube; and a helical member arranged within the cyclone tube in an opposite region of the cyclone tube with respect to the air outlet. The helical member defines or partly defines a helical passage around the center axis from the inlet channel to the cyclone chamber for generating a centrifugal flow in the cyclone chamber. The helical passage has a substantially constant cross sectional area and the helical passage is rotated 360° or less than 360° around the center axis.

A partition skirt device for a cleaning apparatus includes an inner ring and a skirt body. The skirt body includes: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and each extending along a radial direction of the skirt body. Along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body and is recessed relative to the skirt body on a second side surface of the skirt body. On the first side surface of the skirt body, a size of a portion of the collapsing part protruding from the skirt body gradually decreases from the root to the edge part.

A duct is provided and includes a tubular member having an inlet portion, an outlet portion and a central portion interposed between the inlet and outlet portions and a tributary tubular member fluidly coupled to the tubular member at the central portion. The tributary tubular member includes first and second torus sectors defining first and second apertures, respectively, through which an upstream end of the central portion extends. The second torus sector is disposed within the first torus sector to define a sectioned toroidal annulus about the first and second apertures and between an exterior surface of the second torus sector and an interior surface of the first torus sector.

A separator includes an inlet manifold, a throat, and an outlet manifold. The inlet manifold is configured to receive a flow of the mixture. The throat is attached to the inlet manifold. The throat separates heavy species of the mixture from light species of the mixture. The outlet manifold is attached to the throat. The outlet manifold includes an outlet valve and a throttle shaft. The outlet valve includes a cone-shaped inlet and a bowl-shaped outlet. The throttle shaft includes a shaft and a cone-shaped head. The cone-shaped head is positioned within the cone-shaped inlet and the shaft extends through the bowl-shaped outlet. The bowl-shaped outlet, the cone-shaped inlet, and the cone-shaped head are sized and shaped to control the flow of the heavy species through the outlet valve and the flow of the mixture through the separator.
