Tests 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 کاملThe Performance of the 108 Compressor Fitted with Low Stagger Free Vortek Blading
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 ...
متن کاملDesign and Development of a Variable Rotary Compressor
The following paper describes the design and development issues with a variable capacity control 2-stage rolling piston compressor. The control mechanism was based on a gas-bypass control strategy. During the development, design issues surfaced that were not significant in the case of the full capacity version of the compressor. When the capacity was reduced, loss generation mechanisms remained...
متن کاملEvaluation of Implant Collar Surfaces for Marginal Bone Loss: A Systematic Review and Meta-Analysis
Background. It is important to understand the influence of different collar designs on peri-implant marginal bone loss, especially in the critical area. Objectives. The purpose of the present systematic review and meta-analysis was to compare dental implants with different collar surfaces, evaluating marginal bone loss and survival rates of implants. Methods. Eligibility criteria included clini...
