Title: Momentum preserving film-cooling shaped holes

Patent · Tue Aug 16 00:00:00 EDT 2011

OSTI ID:1531692

Shih, Tom I-P; Na, Sangkwon

A system for cooling includes a surface to be cooled and at least one film-cooling hole within the surface for allowing a film cooling jet of coolant to reach the surface, each of the at least one film-cooling hole having a diameter. The at least one film-cooling hole is shaped to preserve momentum of the coolant and assist in preventing entrainment of the hot gases. A method of cooling a surface proximate hot gas includes providing coolant through a w-shaped film-cooling hole to form a cool film between the hot gas and the surface and preserving momentum of the coolant using the w-shaped film-cooling hole to assist in preventing entrainment of the hot gases.
