Attenuation of sound in lined circular ducts
(Cambridge : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)
In the previous report, we have used approximate expressions for the wall impedance for the discussion of sound attenuation in lined circular ducts. For instance, Eq. (2.5) has been used for the wall impedance of a circular ...
Comparison of three dimensional quasi-linear large swirl theory with measured outflow from a high-work compressor rotor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)
A three-dimensional perturbation theory for incompressible strongly swirling flow in an annulus is applied to predict the outflow from a high-work compressor rotor (1)(2). A comparison of the analytical result with the ...
Collapse of the inter-electrode breakdown arc in the magnetic field direction
(Cambridge : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)
A two-dimensional inter-electrode breakdown arc which is uniform in the magnetic field direction is shown to be unstable. The growth time for the instability is of the order of the arc development time. It is unlikely that ...
Accurate, efficient difference operators for the turbulent field equations
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)
Introduction: A potentially powerful method for predicting and describing turbulent flow fields is that of utilizing a finite number of moments of the instantaneous Navier-Stokes equations. This sequence of moment equations ...
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. ...
