Abstract: An assembly for a compartment of a gas turbine engine that includes a housing, a gear, and a baffle disposed about the gear. The baffle includes an upstream portion and a downstream portion. The upstream portion includes an upstream inner wall and an upstream outer wall separated from the gear. The upstream inner wall is positioned between the upstream outer wall and the gear. An upstream flow channel is formed between the upstream inner wall and the upstream outer wall. The downstream portion of the baffle includes a downstream inner wall and a downstream outer wall separated from the gear. The downstream inner wall is positioned between the downstream outer wall and the gear. A downstream flow channel is formed between the downstream outer wall and the downstream inner wall.
