Turbulent mixing in swirling flow
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1978], 1978)
The effect of swirl on the mixing of two gas streams of the same density in coaxial annular geometry has been examined. The flow is studied via a fluorescent tracer, 2-3 biacetyl. Through direct excitation, collisional ...
Three-dimensional incompressible and compressible Beltrami flow through a highly-loaded isolated rotor
(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 ...
Wake behavior downstream of a transonic compressor rotor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1974, 1974)
Measurements of the static pressure resolved in radial and axial directions downstream of a transonic compressor rotor have been harmonically analyzed. The investigation is part of a program addressing the behavior of ...
Exit flow from a transonic compressor rotor
(Cambridge : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)
Summary: The three dimensional unsteady flow field behind a transonic compressor rotor with a design pressure ratio of 1.6 at a tip Mach number of 1.2 has been resolved on the blade-passing time scale, using the M.I.T. ...
Calculation of a self-consistent, low frequency electrostatic field in the drift-kinetic approximation
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine and Plasma Dynamics Laboratory, [1977], 1977)
We derive an asymptotic series in [omega]p -2 , the inverse-square plasma frequency, for the self-consistent, low frequency electrostatic field in tori. The derivation is consistent with the drift-kinetic ordering and may ...
Flutter analysis of a tuned rotor with rigid and flexible disks
(Cambridge : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1979], 1979)
The flutter behavior of a simple tuned rotor with a rigid and a flexible disk is reviewed. In Part A, the rotor assembly is assumed to consist of a rigid disk with N uniform flexible blades attached around the circumference, ...
Stalled flow performance of a single stage transonic compressor
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1978], 1978)
The stalled flow performance of a single stage transonic compressor is examined, using data from the MIT Gas Turbine Laboratory's Blowdown Compressor Facility. Measurements of the blowdown corrected weightflow are included, ...
Small disturbances in compressor annuli with swirl, throughflow and entropy variation
(Cambridge, Mass. : Gas Turbine Laboratory , Massachusetts Institute of Technology, [1970], 1970)
Introduction: Control of the radiation of sound from the compressors and turbines of jet engines depends to a great extent on understanding of the propagation of acoustical modes in the ducting, the general design approach ...
The display of multi-dimensional flows in turbomachinery
(Cambridge, Mass. : Gas Turbine Laboratory , Massachusetts Institute of Technology, [1972], 1972)
Introduction: As part of a general development of computational techniques for multidimensional flows through turbomachine passages and over turbomachine blading at the M.I.T. Gas Turbine Laboratory, display techniques and ...
