Title:
気体冷却媒体流の冷却効果改善の方法及び関連製品
Document Type and Number:
Japanese Patent JP4766736
Kind Code:
B2
Abstract:
A method is described for improving the cooling effectiveness of a fluid (66) which flows through a row of passage holes (68) in a substrate (60) (e.g., a turbine component), out to a high-temperature surface (62) of the substrate (60). The method involves forming a slot (74) over the holes (68), within the high temperature surface (62) of the substrate (60). The slot (74) can be formed within protective coatings (70, 72) applied over the substrate (60). Alternatively, it can be formed partially within the substrate (60), and partially within the protective coatings (70, 72). Movement of a film coolant through the substrate (60) and into the slot (74) results in greater cooling effectiveness. Related articles are also described.
