Channel flow modeling of impingement cooling of a rotating turbine blade
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1984], 1984)
Local heat transfer distributions in impingement cooling have been measured by Kreatsoulas [1] and Preiser [2] for a range of conditions which model those in actual turbine blades, including the effects of rotation. These ...
Flow visualization study of the inlet vortex phenomenon
(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 ...
Experimental investigation of Stator hub treatment in an axial flow compressor
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1981], 1981)
An experiment was carried out to examine the effects, on stator stall margin and performance, of a slotted hub treatment rotating beneath the stator of an axial flow compressor. The compressor was run with this hub treatment ...
Asymmetric inlet flows through axial compressors
(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 ...
Some observations of the vibrations of slender rotating shafts
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1982], 1982)
The linear theory of a slender, initially bowed, rotating shaft is reviewed for both free and forced vibrations, and found to compare well with a simple experiment on such a shaft. The shaft behavior passing through the ...
Computational simulation of unsteady flow in transonic compressor rotor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1986], 1986)
The unsteady flow about a section of a modern first stage transonic compressor rotor was simulated using a finite difference approximation to the two-dimensional, Reynolds averaged, unsteady, compressible, viscous Navier-Stokes ...
Surge dynamics and unsteady flow phenomena in centrifugal compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1988, 1988)
Detailed time resolved measurements of centrifugal compressor surge has been obtained on an automotive turbocharger for two very different compression systems one with a large downstream volume and one with a much smaller ...
Unsteady radial transport in a transonic compressor stage
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1989], 1989)
A technique, based on the operation of a dual-hot wire-aspirating probe with frequency response of at least 18 kHz and uncertainty less than 0.005 to full scale in mass fraction units, has been developed to measure time ...
Rotor wake behavior in a transonic compressor stage and its effect on the loading and performance of the stator
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1980], 1980)
The structure and behavior of wakes from a transonic compressor rotor and their effects on the loading and performance of the downstream stator have been studied experimentally. The rotor is 2 feet in diameter with a tip ...
Three-dimensional vorticity-induced flow effects in highly-loaded axial compressors
(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 ...
