  • MULTIPLEX INERTIAL FILTER, COLLECTOR AND SEPARATOR
    Publication number: 20230405501
    Abstract: 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.
    Type: Application
