    Abstract: Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

    Abstract: A gas-liquid separator has a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A nozzle structure in the housing has a plurality of nozzles that receive the gas-liquid stream and accelerate the gas-liquid stream therethrough to create a plurality of gas-liquid jets. An inertial collector in the housing causes a sharp directional change of the gas-liquid jets, causing separation of liquid particles from the gas-liquid stream to produce the gas stream. The inertial collector has a porous collection substrate. According to the present disclosure, at least one of the following three conditions is met: (a) the porous collection substrate comprises fibers of small diameter and has low packing density; (b) the porous collection substrate comprises oleophobic fibers; and (c) the nozzle structure and the inertial collector are configured to allow for full expansion of the plurality of gas-liquid jets.

    Abstract: An air-liquid separation assembly for separating air and liquid from an air-liquid mixture comprises a housing through which fluid flows, a main separator positioned within the housing, and a sub-separator. The sub-separator is positioned within the housing before or after the main separator and defines a plurality of slots. Each of the plurality of slots is positioned either between adjacent baffles of the sub-separator or between a baffle of the sub-separator and a portion of the housing. The plurality of slots are positioned next to each other in a direction substantially perpendicular to the direction of fluid flow through the housing. The plurality of slots comprises a first subset of slots and a second subset of slots. The second subset of slots extends at a different angle than the first subset of slots such that fluid flows through the first subset of slots and the second subset of slots at different angles.
