Skewed turbulent boundary layers
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1959], 1959)
The problem of predicting the growth of incompressible, skewed, turbulent boundary layers on smooth surfaces is considered. It is supposed that sufficient initial information and a complete knowledge of the external pressure ...
The effect of tip clearance on an axial flow fan
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
The effect of tip clearance on the performance of a single stage axial flow (6000 cfm) fan was investigated for tip clearances ranging from 0.003 in. to 0.252 in. It was found that, at the rated flow, the stagnation pressure ...
Stall propagation in axial compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
A theory of stall propagation in a cascade of airfoils of high solidity has been developed which includes the effects of finite blade chord and of the boundary layer response to changes in angle of attack. The theory is ...
A cascade tunnel for investigation of rotating stall
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1954], 1954)
A test apparatus which will reproduce the rotating stall phenomenon found in axial compressors has been constructed and installed in the main wind tunnel circuit of the Gas Turbine Laboratory. The test section consists of ...
A study of the end wall boundary layer in an axial compressor blade row
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
Turbulent end wall boundary layers in the hub region of axial compressor blade rows have been studied in the Gas Turbine Laboratory. Both analytical and experimental work are presented. An attempt was made to predict the ...
An investigation of cavitating inducers for turbopumps
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1959], 1959)
The experimental performance of two axial inducers is presented. One of the :designs is analytical and includes radial equilibrium considerations. The other is a simple helix, with a constant pitch angle. The performance ...
Boundary layer effects on airfoil lift
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1958], 1958)
A study of the discrepancy in lift between potential flow calculations and experiments was made. In potential flow the fluid is assumed to follow the contour of the airfoil, forming a stagnation point at the geometric ...
Stall propagation in a cascade of airfoils
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1956], 1956)
An experimental investigation of stall propagation in a stationary circular cascade by means of high speed schlieren and interferometer photography is described. This investigation suggests an analytical approach to the ...
Boundary layer on an airfoil in a cascade
([Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1958], 1958)
A study of the turbulent boundary layer on an airfoil in a cascade is presented. The major portion of the observations are on the suction surface of the airfoil. The effect of added diffusion across the cascade due to a ...
Three-dimensional laminar boundary layer in curved channels with acceleration
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1956], 1956)
A theory is developed for two families of three-dimensional laminar boundary layers; namely, for the boundary layer on the parallel plane end walls of a curved channel with logarithmic spiral side walls, and for the boundary ...
