The Performance of the 108 Compressor Fitted with Low Stagger Free Vortek Blading
نویسنده
چکیده
This report contains a description of a large three-stage ~ompressnr whloh has been designed fnr detail thrco dimensional flow investlgat~ons. Particular attention has been pad to the accuracy of measurement on the ng and it 1s shown that the mzin errors are due to the unsteady nature of the flow and to speed fluctuations. Both of these factors are, however, consderably less than those nomm.Uy experienced r.n compressor test work. The test characteristics of the first sot of low stagger fYec vortex blading are presented and campared with van.ous thsoroticdl performance calculations. D~screpancles betifeen the theorctvxil and experimental character istics arc attributed to low devlatlons, and to wry little degeneratson of the sxxal velocity profde. Some rmscellancous results, including a description Of the surging behaviour of the compressor and the effect of blade position upon the measured statx pressure are also yvon.

متن کاملEffect of aging and manufacturing tolerances on multi-stage transonic axial compressor performance
The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...
متن کاملTests on High-Reaction Compressor Blading
Two sets of blading, designed for 120 per cent reaction, and for flow coefficients of 0" 667 and 1.0 respectively, have been tested in the N.G.T.E. low-speed compressor No. 106. The performances were compared with those of corresponding sets of 50-percent reaction blading and with predictions based on simple theoretical methods. The high-reaction bladings both gave efficiencies which were lower...
متن کاملEffect of blade profile on the performance characteristics of axial compressor in design condition
The choice of geometrical shape of the blades has a considerable effect on aerodynamic performance and flow characteristics in axial compressors. In this paper, the effects of the blades shape on the aerodynamic design characteristics are investigated based on Streamline Curvature Method (SCM). Initially, the Streamline Curvature Method (SCM) is used for designing a two-stage axial compressor. ...
