EXHAUST DIFFUSER FOR A GAS TURBINE |
摘要 |
An exhaust diffuser for a gas turbine comprises an annular duct (1). A row of struts (6) is arranged in the duct. In a region downstream of the trailing edges (TE) of the struts (6), the cross-sectional area of the duct decreases to a local minimum (M) and then increases again towards the outlet end (3) of the duct. Thereby the gas flow is locally accelerated downstream of the struts. This stabilizes the boundary layer of the flow in this region and leads to a marked increase in pressure recovery for a wide range of operating conditions. |
