Abstract
A transition duct having an inlet opening and an outlet opening and a body portion extending between the inlet and outlet openings at respective inlet and outlet ends. The inlet opening defines a generally circular cross-section for the body portion and has a geometric center, and the outlet opening defines a generally rectangular arc-like cross-section. The body portion has an internal profile substantially in accordance with coordinate values X, Y and Z at an angle θ, as set forth in Table 1, where each of the X, Y and Z coordinate values are taken at a sweep angle θ passing through the section origin and measured from a first plane defined by the inlet end and increasing toward a second plane defined by the outlet end.
