| 发明名称 | Exhaust diffuser arrangement for a turbine system and method of redirecting a flow | ||
| 摘要 | 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. | ||

| 主权项 | 1. An exhaust diffuser arrangement for a turbine system comprising: an inlet for receiving a flow proximate a last stage bucket of the turbine system, the flow flowing in a first flow direction; and a flow redirecting component comprising: 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;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;a cavity defined by the first wall and the second wall; andan upstream end comprising an opening, wherein the opening is configured to direct a portion of the flow into the cavity. | ||
