摘要： Methods and apparatuses for film cooling of one or more turbine components are provided. A cooling gas flow passage provides a cooling gas to an turbine component with the hot gas path of a turbine. The cooling gas flow passage includes at least one feed aperture operable to receive cooling gas from at least one cooling gas compartment associated with a turbine component. The cooling gas flow passage also includes at least one slot with a converging portion having a first opening and a second opening, where the first opening receives the cooling gas from the feed aperture, and the second opening provides the cooling gas to at least a portion of an outer surface of the turbine component.

摘要： A metered cooling slot disposed in a wall comprising an outer surface that is exposed to a hot gas stream and an inner surface that defines an internal coolant chamber through which a coolant passes, the metered cooling slot comprising: a slot formed within the outer surface elongated in a first direction, the slot comprising a pair of spaced apart, opposing, slot surfaces and a base, the slot surfaces intersecting the outer surface to form a slot outlet opposite the base; and two or more metering apertures formed within the wall, each metering aperture intersecting the inner surface of the wall to form a metering aperture inlet and intersecting one of the pair of slot surfaces to form a metering aperture outlet; wherein: D represents the approximate diameter of at least two of the metering apertures; P represents the approximate distance between the center lines of at least two neighboring metering apertures; and P/D comprises a value within the range of about 4 to 6.
摘要翻译：设置在壁中的计量冷却槽包括暴露于热气流的外表面和限定冷却剂通过的内部冷却剂室的内表面，所述计量冷却槽包括：形成在所述外表面中的槽在第一方向上，所述槽包括一对间隔开的相对的槽表面和基部，所述槽表面与所述外表面相交以形成与所述基座相对的槽出口; 以及形成在所述壁内的两个或更多个计量孔，每个计量孔与所述壁的内表面相交，以形成计量孔入口并与所述一对槽表面中的一个相交，以形成计量孔出口; 其中：D表示至少两个计量孔的大致直径; P表示至少两个相邻计量孔的中心线之间的近似距离; P / D为约4〜6的范围。
