    • Active control of rotating stall in axial compressors 

      Paduano, James D. (James Donald) (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1992], 1992)
      An active control system has been implemented on a low-speed single-stage axial compressor. This control system stabilizes the perturbations which normally lead to rotating stall, thus extending the range of operation of ...

    • Active control of rotating stall in a three-stage axial compressor 

      Haynes, Joel M. (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1993], 1993)
      Stall inception in a three-stage axial compressor has been suppressed over a range of previously unstable operating points through the feedback of velocity perturbations to the inlet flow field. Perturbations were generated ...

    • Control of the unsteady flow in a stator blade row interacting with upstream moving wakes 

      Valkov, Theodore V. (Theodore Valkov) (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1993], 1993)
      A computational study of the unsteady flow in a 2-D stator blade row interacting with upstream rotor wakes has been carried out. A direct spectral-element Navier-Stokes solver has been used for the laminar flow regime ...
