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; and
at least one cooling hole including a connecting passage extending from a first inlet located at the cooled surface, to a first outlet located at the heated surface, the connecting passage defining a downstream flow direction from the first inlet to the first outlet, the connecting passage comprising a metering section fluidly coupled to the first inlet and defining a metered centerline and a diffusing section, downstream of the metering section, defining a diffused centerline, and fluidly coupling the metering section to the first outlet;
wherein the diffusing section terminates in a hood defined at least in part by the wall and covering at least a portion of the diffusing section upstream of the first outlet;
wherein the metered centerline forms an entrance angle with the heated surface;
wherein the diffused centerline forms an exit angle with the heated surface that is less than the entrance angle; and
wherein the at least one cooling hole is a set of cooling holes including a first cooling hole and a second cooling hole located downstream from the first cooling hole relative to a direction of the hot gas fluid flow, 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.
