Download or read book An Annular Gas Seal Analysis Using Empirical Entrance and Exit Region Friction Factors written by David Alan Elrod and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wall shear stress results from stationary-rotor flow tests of five annular gas seals are used to develop entrance and exit region friction factor models. The friction factor models are used in a bulk-flow seal analysis which predicts leakage and rotor-dynamic coefficients. The predictions of the analysis are compared to experimental results and to the predictions of Nelson's analysis (1985). The comparisons are for smooth-rotor seals with smooth and honeycomb-stators. The present analysis predicts the destabilizing cross-coupled stiffness of a seal better than Nelson's analysis. Both analyses predict direct damping well and direct stiffness poorly.

Download or read book Rotordynamics 92 written by Michael J. Goodwin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designers and operators of rotating machinery have to deal with the effects of machine vibration and wear. The increasing demands for quieter machine operation, longer machine life and a greater efficiency of operation have led to the use of sophisticated design aids. Research into rotating machinery is therefore of substantial and increasing importance. Rotordynamics '92 provides a record of some of the most recent research methods and results relating to the design and operation of rotating machinery. The conference is international in character and draws on research from a wide range of respected sources.
