Abstract (en)
[origin: WO2012019650A1] Devices, systems and methods according to exemplary embodiments provide diffusers, e.g., as part of a turbo machine 300, with diffuser vanes having S-shaped camber lines 408. Such S-shaped camber lines 408 are defined by functions having an inflection point. Using diffuser vanes 400 having such shapes results in, among other things, an operation characteristic wherein a portion of the diffuser vanes 400 disposed near a leading edge 402 is substantially unloaded when operating at design conditions and wherein the load gradually increases to a maximum loading value towards a middle portion of the diffuser vanes.
