1. An airfoil comprising:
an outer wall defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a stream-wise direction, and between a root and a tip to define a span-wise direction; and
a set of dimples provided on the outer wall, with each dimple of the set of dimples having a non-perforated section including:
a dimple leading edge;
a dimple trailing edge provided aft of the dimple leading edge in the stream-wise direction; and
at least one lateral edge extending between the dimple leading edge and the dimple trailing edge, the at least one lateral edge converging from the dimple leading edge and towards the dimple trailing edge.
