    • The effect of upstream rotor vortical disturbances on the time-average performance of axial compressor stators 

      Valkov, Theodore V. (Theodore Valkov) (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1997, 1997)
      Time-accurate Reynolds-averaged Navier-Stokes simulations have been carried out to investigate the impact of upstream rotor wakes and tip leakage vortices on the loss of a compressor stator. The objective is to (1) identify ...

    • Blade passage flow structure effects on axial compressor rotating stall inception 

      Hoying, Donald Andrew (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1996], 1996)
      A new computational approach has been developed to study the inception of rotating stall in axial compressors. Using this approach the flow structures within the compressor blade passages have been examined in order to ...

    • A numerical investigation of a flutter in a transonic fan 

      Isomura, Kousuke (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1996], 1996)
      The mechanism of the bending mode flutter of a modern transonic fan has been studied using a quasi-3D viscous unsteady code. The type of flutter in the scope of this research is that for a highly loaded blade with a tip ...
