in Titre de série : | Flow Measurement and Instrumentation, Vol.5 No.1 | Titre : | An experimental technique for performing 3D LDA measurements inside whirling annular seals | Type de document : | articles et extraits | Auteurs : | G. L. Morrison, Auteur ; R. E. DeOtte, Auteur ; M. C. Johnson, Auteur ; H. D. Thames, Auteur ; B. G. Wiedner, Auteur | Année de publication : | 1994 | Importance : | p.43-49 | ISBN/ISSN/EAN : | 0955-5986 | Langues : | Français (fre) | Mots-clés : | 3D LDA Flow fields Whirling annular seals | Résumé : | During the last several years, the Fluid Mechanics Division of the Turbomachinery Laboratory at Texas A&M University has developed a unique facility with the experimental capability for measuring the flow field inside journal bearings, labyrinth seals and annular seals. The facility consists of a specially designed 3D LDA system which is capable of measuring the instantaneous velocity vector within 0.2 mm of a wall while the laser beams are aligned almost perpendicular to the wall. This capability was required to measure the flow field inside journal bearings, labyrinth seals and annular seals. A detailed description of this facility along with some representative results obtained for a whirling annular seal are presented.
