an annular outer wall;
an annular inner wall;
an annular channel having a width defined between the outer wall and the inner wall, the channel having an inlet for ingress of a cooling fluid into the channel and an outlet for egress of the cooling fluid from the channel wherein the width of the annular channel continuously decreases between the inlet and the outlet; and
a plurality of vanes disposed within the channel, each vane of the plurality of vanes extending from the outer wall to the inner wall adjacent the outlet,
wherein the outlet is angled such that an exit angle of the cooling fluid is nonzero with respect to the radial direction and is nonzero with respect to the axial direction.
