摘要： A centrifugal separator for removing particles from a fluid stream includes an angular velocity increaser configured to increase the angular velocity of a fluid stream, a flow splitter configured to split the fluid stream to form a concentrated-particle stream and a reduced-particle stream, and an exit conduit configured to receive the reduced-particle stream. An inducer assembly for a turbine engine includes an inducer with a flow passage having an inducer inlet and an inducer outlet in fluid communication with a turbine section of the engine, and a particle separator, which includes a particle concentrator that receives a compressed stream from a compressor section of the engine and a flow splitter. A turbine engine includes a cooling air flow circuit which supplies a fluid stream to a turbine section of the engine for cooling, a particle separator located within the cooling air flow circuit, and an inducer forming a portion of the cooling air flow circuit in fluid communication with the particle separator. A method of cooling a rotating blade of a turbine engine having an inducer includes directing a cooling fluid stream from a portion of turbine engine toward the rotating blade, separating particles from the cooling fluid stream by passing the cooling fluid stream through a inertial separator, accelerating a reduced-particle stream emitted from the inertial separator to the speed of the rotating blade, and orienting the reduced-particle stream by emitting the reduced-particle stream from the inertial separator into a cooling passage in the inducer.

摘要： A centrifugal air cleaning system broadly comprises an insert cartridge including a housing, an inlet, one or more flow guides, a stator, a compression nozzle, an expansion nozzle, and an outlet. The flow guides guide air flowing into the inlet past the stator into the compression nozzle. The stator induces a rotational vortex into the air flow. Air with heavier particles in the air flow is urged to the outside of the rotational vortex. Air with lighter particles and cleaner air is urged to the inside of the rotational vortex. The compression nozzle and the expansion nozzle are aligned to cooperatively form an annular exhaust channel. The air with the heavier particles flows through the annular exhaust channel and the air with the lighter particles and the cleaner air flows to the expansion nozzle to the outlet.

摘要： A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

摘要： A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, a circulating cleaning assembly is provided in the hydroclone region. In yet another aspect of the invention, improved hydroclone intake structures are described.

摘要： A system includes a hydrocyclone liner. The hydrocyclone liner includes a head section having a fluid inlet and an overflow outlet. The hydrocyclone liner also includes a separation section having an underflow outlet and a first sidewall. A diameter of the separation section of an outer surface of the first sidewall is constant along a length of the outer surface of the first sidewall. The head section and the separation section are joined together via a bond at an interface between the head section and the separation section. The hydrocyclone liner includes a sleeve disposed about at least a portion of the head section, the separation section, and the interface. The sleeve is configured to hold the head section and the separation section together if the bond fails.

摘要： Embodiments of the present invention provide an inertial filtration system for air-ingesting machines. The inertial filter 100 may comprise a reducer 133 downstream of a vortex generator. The reducer 133 decreases the area that the airstream flows through, which may increase the angular momentum and the centrifugal forces acting on the particles of the ingested airstream. This may increase the cleaning performance and a decrease in the pressure drop across the inertial filter 100. Generally, the inertial filter functions such that flow components of higher density are separated from the rest of the airstream. The higher density flow components are bled out of the inertial filter 100 via an outlet 135. The remaining flow components flow downstream to compressor section 535.

摘要翻译： 本发明的实施例提供一种用于吸气机的惯性过滤系统。 惯性过滤器100可以包括在涡流发生器下游的减速器133。 减速器133减少气流流过的面积，这可能增加作用在被摄取的气流的颗粒上的角动量和离心力。 这可能增加清洁性能并降低穿过惯性过滤器100的压降。通常，惯性过滤器起作用，使得较高密度的流动分量与气流的其余部分分离。 较高密度的流动部件经由出口135从惯性过滤器100排出。剩余的流动组分在下游流到压缩机部分535。
