Analysis of turbulence and vortex structures by flow mapping [PDF]

open access: yes, 1997
The technique of Particle Image Velocimetry (PIV) flow mapping is reviewed and comparisons made with Laser Doppler Anemometry (LDA). Results are presented showing the application of PlV to the determination of coherent structures in grid-generated ...

Hole-Blade Treatment in High-Speed Axial Compressors

open access: yesDesigns
The effect of a novel blade treatment on the performance characteristics of NASA Rotor 37 is investigated numerically in this study. The treatment includes making special holes in the blade and near the tip section. The impact of the treatment on the end-

Determination of compressor in-stall characteristics from engine surge transients [PDF]

open access: yes
A technique for extracting the in-stall pumping characteristics for an axial flow compressor operating in an engine system environment is developed. The technique utilizes a Hybrid computer simulation of the compressor momentum equation into which actual

Effect of impeller tip clearance on cavitation in an axial-flow pump

open access: yesEngineering Science and Technology, an International Journal
Cavitation in axial-flow pumps reduces efficiency, induces noise and vibration, and causes wear on metallic components. The existence of a tip clearance, coupled with the high rotational speed of the impeller, creates a favorable condition for cavitation

Investigation of rotor blade element airloads for a teetering rotor in the blade stall regime (second wind tunnel test) [PDF]

open access: yes
A test was conducted in the NASA-Ames 7 x 10 ft low speed wind tunnel on a seven-foot diameter model of a teetering rotor. The objectives of the test were: (1) acquire pressure data for correlation with laser and flow visualization measurements; (2 ...
