A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.

A gas-liquid separator includes the inlet pipe and an inner pipe. The inlet pipe receives a swirling flow generating ribbon, and includes an exhaust port through which a separated gas flows out and a drain port through which a separated liquid flows out. The outer diameter of the inner pipe is smaller than the inner diameter of the inlet pipe. An end of the inner pipe is inserted into the exhaust port and is open at a location downstream of the swirling flow generating ribbon. A terminal end of the swirling flow generating ribbon (30) includes a first terminal edge and a second terminal edge. The first and second terminal edges connect a first terminal end point, a second terminal end point, and a middle terminal end point.

A swirling flow generator for gas-liquid separation includes a swirling flow generating ribbon that swirls a gas-liquid two-phase fluid flowing through an inlet pipe to guide a liquid toward an inner surface of the inlet pipe by centrifugal force. A terminal end of the swirling flow generating ribbon where the gas-liquid two-phase fluid flows out includes a first terminal edge and a second terminal edge. The first and second terminal edges connect a first terminal end point, a second terminal end point, and a middle terminal end point. The first terminal end point is in one of radially outward ends and the second terminal end point is in the other of the radially outward ends. The middle terminal end point is closer to the side where the gas-liquid two-phase fluid flows in than the first and second terminal end points and is on an axial line.

A ram circuit for an aircraft includes a ram inlet housing, a ram outlet housing, a heat exchanger, a ram air fan, and a particle separator. The ram inlet housing includes a chamber and an inlet configured to receive air. The ram outlet housing is fluidly connected to the ram inlet housing. The heat exchanger is disposed between and fluidly connected to the inlet housing and the outlet housing. The ram air fan is disposed in the outlet housing and includes a motor with a cooling inlet. The particle separator includes an outer inlet and a clean air outlet. The outer inlet is configured to receive ram air from the chamber of the ram inlet housing and faces into a flow of air passing through the chamber. Clean air is discharged through the clean air outlet which is fluidly connected to the cooling inlet of the motor.

A cyclonic particle separator (126) may include a housing (130) including a cylindrical sidewall (132) having a plurality of flow entry ports (134). A cover member (136) closes a first end (138) of the cylindrical sidewall (132), and a mounting member (140) having a flow exit opening (160) defined therethrough is at a second end (142) of the cylindrical sidewall (132). At least one particle exit passage (176) is defined in the housing (130). Each of the plurality of flow entry ports (134) includes a flow directing surface angled to direct a gas flow from upstream of the housing (130) to enter the housing (130) in a tangential direction relative to the cylindrical sidewall (132), causing a cyclone vortex. The cyclone vortex acts to separate particles from the gas flow.
