A turbomachinery assembly has a fluid inlet positioned to facilitate the passage of a fluid. The turbomachinery inlet may need a device which can produce inlet swirl or no swirl based on the operation conditions. In this invention, an inlet swirl device is designed to produce the inlet swirl with only one asymmetric automatic valve. No actuator is needed to control the valve. The valve opening is automatic adjusted based on the inlet flow rate. An inlet vane ring assembly is disposed adjacent the inlet and includes a plurality of vanes in the circumferential direction. The vane ring is not movable, but can produce different magnitudes of swirl.

A mid-turbine frame for a gas turbine engine includes an inner frame case. A bearing support member is located adjacent the inner frame case. At least one spoke is attached to the inner frame case. A passage extends through at least one spoke, the inner frame case, and the bearing support member.

The invention relates to a device for controlling the swirl of a fluid (2) flowing in a pipeline (1). The invention was based on the object of creating a device with which the adaptation of the swirl (2B) of a fluid (2) flowing in a pipeline (1), even in the case of constantly changing initial swirl (2B), to the desired flow conditions in the pipeline (1) is possible. Said object is achieved in that a swirl measuring device (4) and a swirl control device (6) are provided at predetermined positions of the pipeline (1), and the device has an evaluation and encoder unit (5), wherein, in the presence of differences between the measured actual swirl (2B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit (5), and the swirl control device (6) corresponds with the evaluation and encoder unit (5) and, by means of the swirl control device (6), the present swirl (2B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.

A diffuser and deswirl flow structure includes a plurality of tube structures with an outer wall that is hollow and elongate and that extends between a first portion and a second portion. The plurality of tube structures is disposed in an annular arrangement about the longitudinal axis. The flow structure also includes a plurality of flow passages extending through the tube structures. The plurality of flow passages extend from the first portion to the second portion, respectively. The plurality of flow passages respectfully include a diffuser portion, which is proximate the first portion and configured to diffuse a fluid flow from a compressor wheel. The plurality of flow passages respectfully include a deswirl portion, which is proximate the second portion and configured to deswirl the fluid flow from the diffuser portion. The outer wall defines the diffuser portion and the deswirl portion. The outer wall is self-supporting.

A throttle valve for a centrifugal compressor includes a body having a central passage and one or more diverter flow paths. The central passage is formed by an inner surface of the body, each diverter flow path has an inlet and an outlet, and the one or more diverter flow paths are configured to induce a swirl within a fluid flow through the central passage while a portion of the fluid flow passes through the one or more diverter flow paths. The throttle valve also includes at least one blade disposed within the central passage. The at least one blade is configured to direct the portion of the fluid flow to the inlets of the one or more diverter flow paths while the at least one blade is in a partially open position.

An assembly for removing particles from a fluid stream includes a first particle remover having a main flow outlet emitting a first reduced-particle stream and a scavenge flow outlet emitting a particle-laden stream, as well as a second particle remover fluidly coupled to the scavenge flow outlet and emitting a second reduced-particle stream.

A particle separator associated with a compressor section of a gas turbine engine includes a duct that defines a fluid flow path from a diffuser to a deswirl section. The duct includes a curved portion between an outlet of the diffuser and an inlet of the deswirl section. The curved portion is configured to have at least one low velocity region and a high velocity region. The particle separator includes at least one cluster of inlet passages defined at the at least one low velocity region. The particle separator includes a scavenge plenum coupled to the duct and in fluid communication with the at least one cluster of inlet passages. At least one outlet slot is defined through the duct downstream of the at least one cluster of inlet passages in the high velocity region and is in fluid communication with the scavenge plenum.

An airfoil assembly for a turbine engine can include an airfoil having an outer wall bounding an interior, and an insert located within the interior with a space between the insert and airfoil outer wall. A cooling hole can pass through the insert with an outlet fluidly coupled to the space between the insert and outer wall.

The exhaust mixer can have a conduit extending around a central axis, and along the axis to a trailing edge, the conduit extending between a radially-outer bypass path and a radially-inner core gas path, the conduit having a plurality of apertures spaced-apart from one another around the circumference of the conduit and fluidly connecting the bypass path to the core gas path upstream of the trailing edge.

A centrifugal compressor for a chiller system includes a casing having an inlet portion and an outlet portion, a recirculation structure including a recirculation path and a recirculation discharge cavity, an impeller disposed downstream of the recirculation discharge cavity, a plurality of recirculation discharge guide vanes disposed to surround the recirculation discharge cavity, and a diffuser disposed in the outlet portion downstream of the impeller. The recirculation structure is configured to impart a swirl to a flow of refrigerant into the inlet portion. The recirculation path supplies the refrigerant from the diffuser to the recirculation discharge cavity. The recirculation path includes a recirculation pipe that introduces the refrigerant toward the plurality of recirculation discharge guide vanes. An annular groove is disposed between the recirculation pipe and the plurality of recirculation discharge guide vanes. An annular plate is disposed between the annular groove and the recirculation discharge cavity.
