Asymmetric inlet flows through axial compressors
(Cambridge : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1980], 1980)
A new analytical method is proposed for the study of flow through highly-loaded turbomachine stages. The technique is used in the present study in order to: (i) analyze the three-dimensional induced effects of the viscous ...
Three-dimensional vorticity-induced flow effects in highly-loaded axial compressors
(Cambridge : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1980], 1980)
A new analytical method is proposed for the study of flow through highly-loaded turbomachine stages. The technique is used in the present study in order to: (i) analyze the three-dimensional induced effects of the viscous ...
Effects of compressor endwall suction and blowing on stability enhancement
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1988], 1988)
An experimental investigation was carried out to examine the effects on stall margin of flow injection into, and removal out of, the endwall region of an axial compressor blade row. A main goal was to identify the mechanism ...
UNSFLO : a numerical method for unsteady inviscid flow in turbomachinery
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1988, 1988)
Introduction: There are four principal sources of unsteadiness in a single stage of a turbomachine in which there is one row of stationary blades (stators) and one row of moving blades (rotors). As shown in Fig. 1.1, ...
Blade scale effects of tip leakage
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1990], 1990)
The effects of blade-tip leakage in a turbine are investigated by modeling the stage as an incomplete actuator disk. It is found that the spanwise flow redistribution due to the gap is such as to produce a uniform unloading ...
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 ...
