Effect of swirl on turbulent jets in ducted streams
(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 ...
Experiments on turbulent boundary layers along a circular cylinder with and without separation
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1967], 1967)
Summary: Experiments were conducted in a turbulent boundary-layer near separation along a circular cylinder with the flow in the axial direction. The pressure gradient along the axis of the cylinder could be varied such ...
Unconventional blade design for compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1969], 1969)
One of the factors causing the low efficiency of axial flow compressors operating at decreased flow rates is the flow separation at blade extremities. To postpone this tendency to separate to lower flow rates, compressor ...
A light scattering investigation of droplet growth in nozzle condensation
(Cambridge, Mass., Gas Turbine Laboratory, Massachusetts Institute of Technology, 1969, 1969)
An experimental and theoretical study has been made of the condensation of water vapor (with air carrier) in a supersonic nozzle in order to investigate the possible existence of condensate droplets which are substantially ...
Boundary layer separation ; preliminary report
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1962], 1962)
The phenomenon of incompressible boundary layer separation and the existing methods of predicting it are discussed. The failure of these theories in many cases clearly indicates a need for further investigation. A program ...
Thin airfoils in rotational flow
(Cambridge, Mass : Massachusetts Institute of Technology, [1965], 1965)
The problem of rotational or shear flow about thin airfoils has been investigated theoretically and experimentally. The theoretical approach is based on the concept of a lifting line in a bounded shear flow whose primary ...
Wake induced blade forces in turbo-machines
(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 ...
Temperature wake in an adverse pressure gradient
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1961], 1961)
A study is made of the flow pattern resulting from the presence of a temperature wake in a uniform velocity field subjected to various adverse pressure gradients. Dimensionless temperature profiles and velocity profiles ...
A study of outlet guide vanes
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1963], 1963)
A criterion for design of unstalled compressor blades has been proposed, and a set of outlet guide vanes has been designed according to this criterion and has been tested. A typical compressor stator and outlet guide vane ...
The development of a perturbed, incompressible, turbulent boundary layer
(Cambridge, Mass. : Gas Turbine Laboratory , Massachusetts Institute of Technology, [1969], 1969)
The response of a fully-developed equilibrium turbulent boundary layer to a small disturbance was observed experimentally under low-Mach number conditions: a turbulent boundary layer in an axisymmetric channel under zero ...
