A seal for a rotating machine; the seal (6; 106; 206; 306) comprising at least one row of teeth (15a, 15b), the row extending from a first side (6a) to a second side (6b) along an axial direction (B); at least one cavity (16) arranged between respective two adjacent teeth (15a, 15b) of the row of teeth (15a, 15b); wherein at least one of the teeth (15a, 15b) has a first and a second surface (20a, 21a; 20a, 20b) which extend transversely to the axial direction (B), and a third surface (22a, 22b) which extends between the first and the second surface (20a, 21a; 20a, 20b) and transversely thereto; wherein the third surface (22a, 22b) is shaped so as to divert the incoming flow (F) towards the cavity (16a, 16b) adjacent to the second surface (21a, 21b). |
