    • Effects of inlet conditions on centrifugal diffuser performance 

      Deniz, Sabri (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1997], 1997)
      This report examines the influence of inlet flow conditions, including Mach number, flow angle, blockage, and axial flow non-uniformity, on the performance and operating range of a straight channel centrifugal compressor ...

    • Effects of non-axisymmetric tip clearance on axial compressor performance and stability 

      Graf, Martin Bowyer; Wong, Thomas S. (Thomas Sheung); Greitzer, E. M. (Edward M.), 1941-; Marble, Frank E.; Tan, Choon Sooi; e.a. (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1997], 1997)
      The effects of circumferentially non-uniform tip clearance on axial compressor performance and stability have been investigated experimentally and analytically. A theoretical model for compressor behavior with non-axisymmetric ...

    • Active stabilization of rotating stall and surge in a transonic single stage axial compressor 

      Weigl, Harald Jürgen (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1997, 1997)
      Rotating stall and surge have been stabilized in a transonic single-stage axial compressor using active feedback control. The control strategy is to sense upstream wall static pressure patterns and feed back the measured ...
