Long description: Die Optimierung dynamischer Dichtsysteme ist eine kostengünstige Methode zur Erhöhung der Wirkungsgrade, Lebensdauer und Betriebssicherheit von Turbomaschinen. Zuverlässige und effiziente Dichtsysteme lassen sich nur realisieren, wenn die Anstreifvorgänge zwischen rotierenden und statischen Komponenten sowie ihre Folgen schon bei der Auslegung berücksichtigt und im Betrieb beherrscht werden können. Bis heute sind die physikalischen Vorgänge beim Anstreifen jedoch nur unzureichend verstanden und es fehlen zuverlässige Modellierungsansätze für ihre Vorhersage. Die vorliegende Arbeit liefert einen essentiellen Beitrag zum Verständnis des Anstreifverhaltens und somit zur Optimierung einlaufender dynamischer Dichtsysteme mit Fokus auf Labyrinthdichtungen mit Einlaufbelägen aus Hohlkörperstrukturen. Mit Hilfe aufwändiger experimenteller Untersuchungen wird in dieser Arbeit ein tiefergreifendes physikalisches Verständnis der Anstreifvorgänge bereitgestellt. Die experimentell gewonnenen Erkenntnisse bilden schließlich die Grundlage für die Entwicklung eines Modellierungsansatzes, der erstmals unter Berücksichtigung aller Einflussparameter die zuverlässige Vorhersage des Anstreifverhaltens einlaufender Labyrinthdichtungen ermöglicht.

The gas foil bearing (GFB) technology is a key factor for the transition to oil-free rotating machinery. Among numerous advantages, GFBs offer the unique ability to be lubricated with working fluids such as refrigerants. However, the computational analysis of refrigerant-lubricated GFB–rotor systems represents an interdisciplinary problem of enormous complexity. This work pushes forward existing limits of feasibility and establishes a new strategy that enables stability and bifurcation analyses.

" ... provides up-to-date information on the science, practice and technology of lubrication, wear prevention and friction control. This multidisciplinary field is approached from a practical standpoint, equipping designers, research and development engineers, mechanical and lubrication engineers, managers and scientists with the information that will enable them to minimize the cost of moving parts. Thus machinery can be made more efficient, more reliable and more cost effective."

Since 2004 the Springer Handbook of Nanotechnology has established itself as the definitive reference in the Nanoscience field. It integrates the knowledge from nanofabrication, nanomechanics, materials science, and reliability engineering in just one volume. Reflecting further developments, the new edition has grown from six to eight parts and from 38 to 58 chapters. Existing chapters have been thoroughly updated and new material has been added to cover developing fields such as bionanotechnology, nanorobotics, and NEMS/MEMS reliability. This classic reference book addresses mechanical and electrical engineers, materials scientists, physicists and chemists who work either in the nano area or in a field that is or will be influenced by this new key technology. From the reviews of the first edition: "The strong point is its focus on many of the practical aspects of nanotechnology... Anyone working in or learning about the field of nanotechnology would find this an excellent working handbook.’’ IEEE Electrical Insulation Magazine "Outstandingly succeeds in its aim… It really is a magnificent volume and every scientific library and nanotechnology group should have a copy." Materials World "The integrity and authoritativeness… is guaranteed by an experienced editor and an international team of authors which have well summarized in their chapters information on fundamentals and applications." Polymer News Key Topics Nanostructures Nanomechanics NEMS /MEMS BioNEMS/BioMEMS Micro/Nanofabrication Micro/Nanodevice Reliability Scanning Probe and Force Microscopies Nanotribology and Nanorheology Nanorobotics Molecular Technology Bionanotechnology Therapeutic Nanodevices Industrial Applications Social and Ethical Aspects Features Covers basic concepts, theory, materials, properties, and fabrication. Contains over 1500 two-color illustrations Numerous comprehensive materials data tables. Features exhaustive references to approved data. A detailed index and fully searchable CD-ROM guarantee quick access to data. .
