A particulate filtration device is suggested, comprising an inlet for an inflow of a gas stream which is particle-laden, an outlet for an outflow of the gas stream having a significantly reduced particulate load, a main filter section, which is arranged within a flow path of the gas stream between the inlet and the outlet and which comprises a filtration medium, and a prefilter chamber, which is arranged upstream of the main filter section and which comprises an inertial filter element, having several perforations, wherein the perforations of the inertial filter element are arranged within the flow path of the gas stream in such a way that when the flow path of the gas stream is passing through the perforations, an inertial separation of the particulates from the mean flow path of the gas stream is achieved.

Methods and systems are provided for a multiplexed phase separating inertial filter that is composed of helical through holes generating centrifugal separating forces. In one example, the inertial filter may be a planar porous material with an array of helical channels, each helical channel of the array of helical channels extending from a top surface of the porous material to a bottom surface of the porous material.

Mitigating particulate intrusion to an air intake system of a gas turbine system with intrusion protective coatings tailored to locale of operation. A particulate intrusion protective coating is applied to a surface of a component of the air intake system to mitigate ingress of particulates within the air intake system and the gas turbine system. The particulate intrusion protective coating includes one or more particulate ingress influencing properties tailored to the common attributes of the particulates associated with the locale of operation of the gas turbine engine and the air intake system. The particulate ingress influencing properties affect rebounding and coalescing characteristics of the particulates at a point of impact with the applied surface having the particulate intrusion protective coating, entraining the particulates at the point of impact and inhibiting further ingress along an inlet air flow path of the air intake system into the gas turbine engine.

An engine system includes a charge-air cooler, a separator for separating water from an airflow, and an engine. The separator causes an airflow from the charge-air cooler to strike one or more partitions and change directions via a serpentine path such that water is separated out of the airflow before the airflow reaches the engine.

An inlet particle separator system includes a shroud section and a hub section that is at least partly surrounded by the shroud section. The hub section is spaced apart from the shroud section. The inlet particle separator system also includes a flow passageway with an air inlet defined between the hub section and the shroud section. The flow passageway branches downstream of the air inlet into a main passage and a pre-cleaner passage. The main passage is defined between the hub section and the shroud section. The pre-cleaner passage includes a pre-cleaner inlet and extends at least partially through the hub section. Furthermore, the system includes a splitter that divides the main passage into scavenge and engine flow paths. The pre-cleaner inlet is partly defined by a first surface of the hub section. The first surface faces substantially in an upstream direction toward the air inlet.

This disclosure provides a two-phase separator device for separating condensate or particulate from a gas stream. In some implementations, the separator device removes water from air and may operate under micro-gravity conditions. The gas stream flows through the two-phase separator device and passes through a rotatable vane assembly along a flow path without being redirected in another flow path. Condensate or particulate in the gas stream is impacted by a plurality of vanes of the rotatable vane assembly, and the condensate is captured by features formed within the plurality of vanes. The captured condensate is accelerated radially outwardly along the each of the plurality of vanes towards a sloped inner wall, and further moved along the sloped inner wall in a direction against the flow path of the gas stream during rotation.
