Abstract:
1. A system for mixing flows from a compressor, the system comprising: an ejector for receiving a first flow and a second flow from said compressor, and an ejector output for combining said first and second flows into a third flow; said first flow having a first pressure and a first temperature, and said second flow having a second pressure and a second temperature, wherein said first and second pressures are different and said first and second temperatures are different; a bypass flow connecting said first flow and said third flow, the third flow having a third pressure and a third temperature, wherein the third pressure is different from said first and second pressures and the third temperature is different from said first and second temperatures; a mixer for combining only said bypass flow and said third flow to provide a fourth flow, said fourth flow having a pressure and temperature intermediate said pressure and temperature of the bypass flow and the third flow, and where said fourth flow is input to a turbine; wherein said bypass flow intersects with said third flow at a mixing angle that reduces back pressure on the ejector output, said mixing angle is at least about 0 degrees, but not more than about 90 degrees.
