Abstract
A diffuser for a turbo machine, such as an exhaust diffuser for an industrial gas turbine engine, the diffuser including a plurality of struts connecting the inner shroud of the diffuser to the outer shroud, where the struts have trailing edges with a step shape to reduce the losses and improve the performance of the diffuser. The stepped shaped trailing edge includes three or more steps with the middle step being the longest in the chordwise direction and the remaining steps being symmetric about the chord of the strut.
