ABSTRACT:
A wall enclosing a hot gas path, the wall including a cooling cavity formed between an inner wall and an outer wall, and a plurality of pins extending between walls with a plurality of turbulators within the cooling passage to promote turbulence within the cooling air flow. The turbulators form a zigzag arrangement. The turbulators are angled at about 45 degrees or about 60 degrees from the cooling air flow path. Turbulators are arranged on one wall or both walls, and can be arranged directly across from turbulators on the opposite wall, or offset below and at a mirror image of the other wall.
