Luminescent visualization of molecular and turbulent transport in a plane shear layer
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine Laboratory, [1977], 1977)
The purpose of this work is to contribute to the fundamental understanding of fluid turbulence by visualizing its detailed flow structures. Examination of these coherent structures gives information about the turbulent ...
The interaction of sound with turbulent flow
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1977], 1977)
Introduction: In the now classical theory of sound from turbulent flow by Lighthill boundaries were not considered. Further, it was assumed that the turbulent flow field was not altered by sound emission. For closed systems, ...
Spherical pressure probe for retrieving freestream pressure and directional data
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1977], 1977)
A spherical pressure probe designed to time resolve the total and static pressure and freestream radial and rotational flow angles in turbomachine flow fields was found to produce accurate results for flow angles over a ...
An application of advanced statistical techniques to forecast the demand for air transportation
(Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1977], 1977)
Introduction and objectives: For some time now regression models, often calibrated using the ordinary least-squares (OLS) estimation procedure, have become common tools for forecasting the demand for air transportation. ...
Uniform-inlet three-dimensional transonic Beltrami flow through a ducted fan
(Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine Laboratory, [1977], 1977)
Introduction: This report is a continuation of a line of analytical treatment of three dimensional flows in compressor or ducted fans. In the earlier theories [1,2,9,10], the blade row is modelled as a set of spinning ...
Ground controlled precision landing delivery in the presence of radar disturbances
(Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1977], 1977)
Introduction: The purpose of Air Traffic Control is to ensure separation of aircraft in the most efficient manner possible. The need for efficiency is becoming more important as air traffic continues to increase at a high ...
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 ...
