Abstract
A component for a centrifugal degasser for an air/oil mixture of a turbomachine is disclosed. The degasser rotates about an axis of symmetry, forming an annular chamber for centrifugal separation of the mixture. The chamber forms a fluid passage duct, one inlet of which is oriented axially for supplying the chamber with the mixture, and a first outlet of which is oriented radially inwards for discharging the deoiled air separated from the mixture. The chamber also includes at least one second oil outlet oriented radially outwards and intended to discharge the oil separated from the mixture to the outside of the degasser. The chamber has longitudinal walls passing radially therethrough, at least one of the surfaces of the longitudinal walls having surface structures and/or corrugations arranged to form obstacles to a flow of the mixture along the surface of the longitudinal walls.
