A hollow airfoil is provided having a leading edge, a trailing edge, and a wall including a suction side portion and a pressure side portion. The wall, which includes an interior surface and an exterior surface, surrounds a first cavity and a second cavity, separated from one another by a rib extending between the suction side and pressure side wall portions. The first cavity is contiguous with the leading edge. The airfoil further includes a coolant flow splitter attached to the wall interior surface within the first cavity, and at least one metering orifice disposed in the rib. The metering orifice(s) are substantially aligned with the coolant flow splitter, such that cooling air passing through the metering orifice(s) encounters the flow splitter. The flow splitter splits the cooling air flow and directs it along the wall interior surface.
