    • Asymmetric inlet flows through axial compressors 

      Tan, Choon Sooi (Cambridge : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1980], 1980)
      A new analytical method is proposed for the study of flow through highly-loaded turbomachine stages. The technique is used in the present study in order to: (i) analyze the three-dimensional induced effects of the viscous ...

    • Effect of swirl on turbulent jets in ducted streams 

      Morton, Harmon Lindsay (Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine Laboratory, [1968], 1968)
      An experimental and theoretical program of research has been carried out to determine the effect of swirl on the mixing of a turbulent jet in a ducted stream. The term swirl is used to describe a flow pattern within the ...

    • Flow visualization study of the inlet vortex phenomenon 

      De Siervi, Francesca (Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1981], 1981)
      The inlet vortex phenomenon was experimentally investigated in a water tunnel, using hydrogen bubble flow visualization techniques. Several inlet ambient flow combinations were studied, including an inlet and ground plane ...

    • Quantitative investigation of inlet vortex flow field 

      Shin, Hyoun-Woo; Shippee, Cheryl (Cheryl Lynn) (Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1984], 1984)
      A quantitative investigation of the flow field of an inlet in cross-wind has been carried out for various operating conditions, including flow regimes representative of aircraft engine inlets at take-off. The measurements ...

    • A secondary flow approach to the inlet vortex flow field 

      Viguier, Henri Charles (c1980, c1980)
      A theoretical study is presented of the fluid mechanics of the inlet vortex (or ground vortex). The vorticity field associated with this phenomenon is investigated using a secondary flow approach. In this approach the flow ...

    • Three-dimensional incompressible and compressible Beltrami flow through a highly-loaded isolated rotor 

      Tan, Choon Sooi (Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1979], 1979)
      An analysis is proposed for the three-dimensional incompressible and compressible Beltrami flow through a heavily loaded isolated rotor. It is found that, in agreement with previous analyses on disturbances in swirling ...

    • Three-dimensional vorticity-induced flow effects in highly-loaded axial compressors 

      Tan, Choon Sooi (Cambridge : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1980], 1980)
      A new analytical method is proposed for the study of flow through highly-loaded turbomachine stages. The technique is used in the present study in order to: (i) analyze the three-dimensional induced effects of the viscous ...

    • Vortex decay in a conical diffuser 

      So, Kwan-Lok (Cambridge, Mass. : b Gas Turbine Laboratory, Massachusetts Institute of Technology, [1964], 1964)
      The behavior of vortex flow in a conical diffuser has been studied in this report. The flow considered here is a steady, incompressible, axially symmetric one. The present experimental investigation has resulted in the ...

    • Wake induced blade forces in turbo-machines 

      Lefcort, Malcolm D. (Malcolm David) (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1962], 1962)
      The wake interaction problem in a turbo-machine has been simulated in a water table. The pressure distribution over a compressor blade during the passage of a wake shed by an upstream wake generator has been determined ...
