发明名称 Exhaust diffuser
摘要 An exhaust diffuser includes an outer shroud and an inner shroud radially separated from the outer shroud so as to define a fluid passage between the outer shroud and the inner shroud. A strut extends between the outer shroud and the inner shroud. The strut generally includes an outer surface, a leading edge, a trailing edge, a first side and a second side. At least one turbulator may be positioned along a radial span of the strut. The at least one turbulator extends generally outwardly from the strut outer surface. The turbulator extends across the leading edge of the strut from the first side to the second side of the strut.

主权项 1. An exhaust diffuser, comprising; a. an outer shroud, wherein the outer shroud comprises a double wall construction including an inner wall radially spaced from an outer wall so as to define an airspace therebetween; b. an inner shroud radially separated from the outer shroud to define a fluid passage between the outer shroud and the inner shroud; c. a strut extending between the outer shroud and the inner shroud, the strut having an outer surface, a leading edge, a trailing edge, a first side and a second side, wherein the strut is stationary between the outer shroud and the inner shroud; and d. at least one turbulator positioned along a radial span of the strut and that extends outwardly from the strut outer surface, the at least one turbulator extending across the leading edge of the strut from the first side to the second side of the strut; e. wherein the at least one turbulator reduces aerodynamic losses across the strut, the inner shroud and the outer shroud resulting from flow separation of combustion exhaust gases flowing from a turbine section of a gas turbine and into the exhaust diffuser at tangential flow angles.
