RISThroughflow Analysis of a Multistage Compressor Operating at Near-Stall Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Because of their speed and efficiency, two–dimensional steady flow calculations will continue to play a significant role in the compressor aerodynamic design process. For this reason, an assessment ...
Axial Compressor Stator Aerodynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axisymmetric, through-flow calculations, currently the “backbone” of most multistage turbomachinery design systems, are being pushed to their limit. This is due to the difference between the ...
Through-Flow Analysis of a Multistage Compressor: Part I—Aerodynamic Input
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-flow theory is at the heart of turbomachinery aerodynamic design in that it provides the incidence and Mach number distributions that are ultimately used to define the rotor and stator ...
Through-Flow Analysis of a Multistage Compressor: Part II—Analytical-Experimental Comparisons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-flow theory is at the heart of turbomachinery aerodynamic design in that it provides the incidence and Mach number distributions that are ultimately used to define the rotor and stator ...
A Trace Gas Technique to Study Mixing in a Turbine Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental technique to study mixing in a turbine stage is demonstrated. An axisymmetric, radial temperature profile at the inlet to the first stator of a large-scale, low-speed, single-stage, ...
Through-Flow Modeling of Axial Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-flow analysis, which is at the heart of the aerodynamic design of turbomachinery, requires as aerodynamic input a row-by-row description of the airfoil loss, deviation, and blockage. Loss ...
Measurement of Turbine Rotor Blade Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurement methods for obtaining various types of experimental data on a turbine rotor blade are discussed in this paper. A variety of different types of measurements have been taken in the ...
An Investigation of Axial Compressor Rotor Aerodynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The detailed nature of the three-dimensional flow over the blading, and in the wake, of an isolated compressor rotor has been studied experimentally in a large scale rotating rig. A variety ...
The Effects of Turbulence and Stator/Rotor Interactions on Turbine Heat Transfer: Part I—Design Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined experimental and analytical program was conducted to examine the effects of inlet turbulence, stator–rotor axial spacing, and relative circumferential spacing of first and second stators ...
The Effects of Turbulence and Stator/Rotor Interactions on Turbine Heat Transfer: Part II—Effects of Reynolds Number and Incidence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Part I of this paper presents airfoil heat transfer data obtained in a rotating turbine model at its design rotor incidence. This portion of the paper presents heat transfer data obtained in ...
