Abstract: Methods, systems, and apparatuses for high efficiency exhaust duct flow path. In an embodiment, an exhaust duct flow path may be created by calculating the efficiency of an exhaust duct flow path with an initial measurement. The initial measurement may be changed and the efficiency analyzed. Then the efficiency of the exhaust duct flow path with the changed measurement may be compared to the efficiency of the exhaust duct flow path with the initial measurement.

Abstract: A diffuser assembly is provided herein. In certain embodiments, the diffuser assembly may include an outer boundary member and an inner boundary member, with the inner boundary member being positioned radially inward of the outer boundary member. The diffuser assembly also may include an exhaust flow path defined between the outer boundary member and the inner boundary member. Further, the diffuser assembly may include at least one flow deflecting member operatively attached to the outer boundary member. The flow deflecting member may be adjustable about the outer boundary member to produce a substantially uniform velocity distribution within the exhaust flow path.

Abstract: A diffuser for a turbine engine includes a first wall that extends circumferentially about a centerline axis of the turbine engine. The diffuser also includes a second wall that extends circumferentially about the centerline axis. At least a portion of the second wall is positioned radially outwardly from at least a portion of the first wall. A flow path is defined by the first wall and the second wall. The flow path extends from an inlet configured to receive an axial flow of a fluid, to a circumferentially extending outlet configured to emit the fluid in a substantially radial direction. The outlet extends asymmetrically about the centerline axis.

Abstract: An exhaust gas diffuser for a turbomachine includes a diffuser supported on a turbine rotor, aligned with an axis of said turbine rotor. The diffuser is configured to re-direct turbine exhaust gas substantially ninety degrees from a first direction of flow along the rotor axis. A plenum chamber is in fluid communication with and surrounds an outlet end of the diffuser. The plenum chamber is in fluid communication with a transition duct adapted to supply the exhaust gas to another turbomachine. The plenum chamber expands in volume between the diffuser and the transition duct.
