INERTIAL PARTICLE SEPARATOR AND PARTICLE BOUNCE CONTROL

摘要

An inertial particle separator (IPS) (102, 200) including an intake air duct (212), a scavenge duct (228) that shares an interior common wall (232) with the intake air duct (212), a clean air duct (230), and a splitter (226). The splitter (226) is configured to split a flow of intake air (214) into a flow of scavenge air (216) and a flow of clean air (218). The IPS (102, 200) also includes a plurality of valleys (302) on the the intake air duct (212). The plurlaity of valleys (302) includes a plurality of troughs (432, 434, 436, 438, 440) and peaks (422, 424, 426, 428, 430) along the interior common wall (232). In addition, each trough (432, 434, 436, 438, 440) of the plurality of valleys (302) extends along a direction of the flow of intake air (214).
