Abstract: An exhaust diffuser is provided having a center body having an inlet adapted for coupling to a turbine. The center body has an outer wall, and a guide member disposed inside the center body. A flow path reducing member is disposed inside the center body. The flow path reducing member is configured to be movable into a first position and a second position. The first position is an inactive position having no impact on an exit flow area of the exhaust diffuser, and the second position is a deployed position that reduces the exit flow area of the exhaust diffuser.

Abstract: An exhaust diffuser arrangement for a turbine system includes an inlet for receiving a flow proximate a last stage bucket of the turbine system, the flow flowing in a first flow direction. Also included is a flow redirecting component. The flow redirecting component includes a first wall having a first side of a concave surface geometry for redirecting the flow and a second side of a convex surface geometry. The flow redirecting component also includes a second wall spaced downstream of the first wall and having at least one flow exit for reducing a boundary layer along the second side of the first wall.
