Title: Non-vaned swirl core configurations

Abstract

A non-circular coolant passage is disclosed, which includes one or more walls axially defining a flow path; an inlet connecting to a first end of the flow path; and an exit connecting to a second end of the flow path, wherein a size of a passage cross-section varies in the axial direction. In certain exemplary embodiments the passage cross-section size varies uniformly, while in others the passage cross-section size varies incrementally. In certain exemplary embodiments, an angular orientation of the passage cross-section varies in the axial direction. The cross-section angular orientation can vary uniformly, incrementally, or a combination of both. In still other embodiments, both the size of the passage cross-section and the angular orientation of the passage cross-section vary in the axial direction. In these embodiments, the passage cross-section size and/or the angular orientation of the passage cross-section can vary uniformly, incrementally, and/or a combination of the two.
