Zusammenfassung:An exhaust diffuser arrangement (10) for a turbine system includes an inlet (12) 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 (30). The flow redirecting component includes a first wall (32) having a first side (34) of a concave surface geometry for redirecting the flow and a second side (36) of a convex surface geometry. The flow redirecting component also includes a second wall (38) spaced downstream of the first wall and having at least one flow exit (50) for reducing a boundary layer along the second side of the first wall.
