Abstract: A turbine component includes an internal surface, an external surface and a cooling hole. The cooling hole includes an inlet disposed on the internal surface, an outlet disposed on the external surface and a flow passage in fluid communication between the inlet and outlet. The flow passage includes a metering section extending from the inlet to a metering end, a diffusion zone extending from the metering end to the outlet, and a hooded region defined by a portion of the diffusion zone covered by a hood. The cooling hole also includes a vane extending across the flow passage, wherein a portion of the vane is disposed within the hooded region.

Abstract: A turbine component includes a rail coolant directing chamber radially outward from an airfoil chamber and radially inward from a tip plate. The chamber includes an inlet fluidly coupled to the airfoil chamber to receive a coolant flow therefrom. A plurality of outlets from the rail coolant directing chamber direct the coolant flow to the at least one rail cooling passage in the rail. At least one directing wall is within the rail coolant directing chamber to direct the coolant flow towards one or more of the plurality of outlets located along at least one of the pressure side wall and an aft region of the suction side wall prior to other outlets.

Abstract: A component is provided and comprises at least one wall comprising a first and a second surface. At least one film cooling hole extends through the wall between the first and second surfaces and has an outlet region at the second surface. The film cooling hole includes a first expansion section being a side diffusion portion and a second expansion section being a layback diffusion portion, wherein the side diffusion portion is upstream and spaced from the layback diffusion portion.
