A centrifugal rotor includes a hub (10) having a longitudinal axis (8), a fluid inlet (20), a first flange referred to as upstream flange (12) and having an opening (22) around the hub (10), a second flange referred to as downstream flange (14) separated from the first flange by blades (16) thus forming ducts each delimited by the first flange (12), the second flange (14) and two blades (16) and extending from the fluid inlet (20) to a peripheral outlet (26), near the peripheral outlet (26) the first flange (12) having a concave zone (32) facing towards the ducts whereas the second flange (14) has a convex zone (34) facing towards the ducts. |
