Abstract

A cooling assembly comprises a cooling chamber disposed inside a turbine assembly. The cooling chamber is configured to direct cooling air inside one or more of a combustion chamber or an airfoil of the turbine assembly. An orthogonally converging diffusing (OCD) conduit is fluidly coupled with the cooling chamber. The OCD conduit is configured to direct at least some of the cooling air out of the cooling chamber outside of an exterior surface of the one or more of the combustion chamber or the airfoil. The OCD conduit is elongated along and encompasses an intersection between a constricting plane and a diffusing plane that are traverse to each other. The OCD conduit has an interior surface with a first distance between opposing first portions of the interior surface. The first distance increases in the diffusing plane at increasing distances along the intersection from the cooling chamber toward the exterior surface. The interior surface of the OCD conduit has a second distance between opposing second portions of the interior surface of the OCD conduit. The second distance between opposing second portions decreases in the constricting plane at the increasing distances along the intersection from the cooling chamber toward the exterior surface.
