Abstract: Embodiments of the present disclosure are directed to a gas flow delivery apparatus and systems of an additive manufacturing system. The gas delivery apparatus comprises a first conduit having an elbow and an outer diameter DA and at least one second conduit fluidly coupled to the first conduit at a mixing region. The mixing region is positioned downstream of the elbow of the first conduit, and the mixing region is at least a distance Z from a center line of the at least one second conduit to the elbow. A diffuser is fluidly coupled to the first conduit downstream of the mixing region, the diffuser comprising an outlet having a perforated plate.

Abstract: A centrifugal separator includes an outer tube, an inner tube, an outlet pipe, and a control mechanism. The outer tube defines at least one outer tube inlet and at least one outer tube outlet. The inner tube is disposed within the outer tube. The inner tube is configured to separate the flow of a first fluid into the flow of a second fluid and a flow of a third fluid by rotation thereof. The outlet pipe is partially disposed within the inner tube and the outer tube. The outlet pipe includes a cross-sectional area. The outlet pipe is configured to channel the flow of the third fluid out of the inner tube and the outer tube. The control mechanism is coupled to the outlet pipe. The control mechanism is configured to regulate the flow of the third fluid by changing the cross-sectional area of the outlet pipe.

Abstract: A centrifugal separator for separating a mixed stream including a first fluid and a second fluid. The separator includes a housing that extends from a first end to a second end. A first flow opening is at the first end, a second flow opening is at the second end, and a third flow opening is at the second end. A rotor assembly within the housing includes a rotor shaft and a cylindrical drum. The cylindrical drum includes an interior including an outer radial portion and an inner radial portion. The outer radial portion is in flow communication with the first flow opening and the second flow opening, and the inner radial portion is in flow communication with the third flow opening. The cylindrical drum is rotatable within the housing such that the first fluid flows along the outer radial portion, and such that the second fluid flows along the inner radial portion.
