A numerical investigation of a flutter in a transonic fan
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1996], 1996)
The mechanism of the bending mode flutter of a modern transonic fan has been studied using a quasi-3D viscous unsteady code. The type of flutter in the scope of this research is that for a highly loaded blade with a tip ...
Effects of inlet conditions on centrifugal diffuser performance
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1997], 1997)
This report examines the influence of inlet flow conditions, including Mach number, flow angle, blockage, and axial flow non-uniformity, on the performance and operating range of a straight channel centrifugal compressor ...
The design of axial inducers for turbo-pumps
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1958], 1958)
In many turbopump applications it is desirable to run the pump at the highest possible speed to minimise the size and weight of the unit and facilitate matching with a drive turbine. Frequently, a limit on rotational speed ...
Comparative study of tip clearance effects in compressors and turbines
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1961], 1961)
The influence of tip clearance on the lift distribution along a blade span was studied on linear compressor and turbine cascades. The wall boundary layer was removed by means of the image technique. The lift distribution ...
Secondary flow and losses in a compressor cascade
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1958], 1958)
Three ways in which secondary flow can be generated in a straight compressor cascade have been investigated. 1. Wakeflow. The inlet flow is characterized by a constant inlet angle and a varying stagnation pressure over the ...
An investigation of rotating stall in a single stage axial compressor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
The rotating stall characteristics of a single stage axial flow compressor were investigated. The number of stall cells and their propagation velocities were found with and without stator blades. The measured velocities ...
FORTRAN program for calculating three-dimensional, inviscid, rotational flows with shock waves in axial compressor blade rows : I--user's manual
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1981], 1981)
Summary: A FORTRAN-IV computer program has been developed for the calculation of the inviscid transonic/supersonic flow field in a fully three-dimensional blade passage of an axial compressor rotor or stator. Rotors may ...
Quantitative investigation of inlet vortex flow field
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1984], 1984)
A quantitative investigation of the flow field of an inlet in cross-wind has been carried out for various operating conditions, including flow regimes representative of aircraft engine inlets at take-off. The measurements ...
Efficient distributed information fusion using value of information based censoring
(2012-07-27)
In many distributed sensing applications, not all agents have valuable information
at all times. Therefore, requiring all agents to communicate at all times can be
resource intensive. In this work, the notion of Value ...
