1. A component for a turbine engine which generates a hot gas fluid flow, and provides a cooling fluid flow, comprising:
a wall separating the hot gas fluid flow from the cooling fluid flow and having a heated surface along which the hot gas fluid flow flows and a cooled surface facing the cooling fluid flow;
a set of cooling holes comprising at least a first cooling hole and a second cooling hole located downstream from the first cooling hole, the first cooling hole comprising a first inlet located at the cooled surface and a first outlet located at the heated surface, the second cooling hole comprising a second inlet located at the cooled surface beneath the first outlet and a second outlet located at the heated surface, where the first outlet and the second outlet each define a modified outlet shape having:
at least one expansion section having an increasing width,
a contraction section downstream of the at least one expansion section and having a decreasing width, and
a constant section upstream of the contraction section.
