Increasing possibilities of computer-aided data processing have caused a new revival of optical techniques in many areas of mechanical and chemical engi neering. Optical methods have a long tradition in heat and mass transfer and in fluid dynamics. Global experimental information is not sufficient for de veloping constitution equations to describe complicated phenomena in fluid dynamics or in transfer processes by a computer program. Furthermore, a detailed insight with high local and temporal resolution into the thermo and fluiddynamic situations is necessary. Sets of equations for computer...

Stellen Sie sich New York, Tokio oder Frankfurt ohne Wolkenkratzer vor. Es wäre unmöglich. Doch der limitierende Faktor für das Wachstum unserer Städte war jahrhundertelang nicht der Mangel an Baumaterial, sondern die menschliche Anatomie: Niemand wollte freiwillig mehr als sechs Stockwerke Treppen steigen. Erst als Elisha Graves Otis im Jahr 1853 bei einer dramatischen Präsentation in New York das Seil seines Aufzugs durchschneiden ließ, um seine revolutionäre Sicherheitsbremse zu demonstrieren, fiel der Startschuss für eine völlig neue architektonische Ära.Dieses faszinierende...
