In a conduit constituting the outlet from turbo machinery such as a turbine or compressor, stall gas having high static pressure and low velocity is collected. This stall gas is then routed through struts-preferably teardrop shaped-to more central low static pressure and high velocity gas flow areas. At these areas, the gas is discharged, preferably through multiple manifold openings. Mixing of the collected high static pressure, low velocity stall gas with the low static pressure, high velocity main stream gas occurs. Turbine noise, vibration, and back pressure are decreased with resulting improvements of efficiency. Variations are illustrated including adaptation of gas flow transfer utilizing turning vanes, fairings, rectangular duct turns, and struts for placement in turbine turbo machine outlets having high turbulence or variable swirl. |
