Abstract

A guide vane assembly including an annular casing and vanes that are coupled to and extend radially inwardly from the annular casing. Each vane includes a first wall, a second wall, a leading edge, a first wall trailing edge, and a second wall trailing edge. The first and second walls are coupled at the leading edge and spaced apart to define a plenum therebetween. The trailing edges are spaced apart to define a gap therebetween. The first wall trailing edge includes a lip extending therefrom toward the second wall, and the second wall trailing edge includes a bulb section extending along at least a portion of a length thereof. The second wall trailing edge is disposed at least partially inside the lip, wherein a substantial entirety of the vane between an outer surface of the second wall and an outer surface of the bulb portion is rounded.
