Available in PDF, EPUB and Kindle. Book excerpt: A selection of invited chapters focusing on developments in the application of Computational Fluid Dynamics (CFD) to compressible or incompressible flows dominated by turbulence effects. These may be applied to complex geometrical configurations or flow-fields in simpler geometries requiring higher-order turbulence modelling, or suitably modified low-order models, to calculate crucial parameters such as instabilities, transition, separation, accurate description of velocity and scalar fields, and local and total forces.

Book excerpt: The Conference Proceedings contains 38 papers presented at the Propulsion and Energetics Panel 73rd Symposium on 'Aircraft Fire Safety' which was held 22 - 26 May 1989 in Sintra, Portugal. The Symposium was arranged in the following sessions: Review of Fire-Related Aircraft Accidents (3); Fire Safety Standards and Research Programmes (6); Aircraft Internal Fires (9); Aircraft External Fires (2); Fire Safety of Military Weapon Systems (3); Fire Hardening by Advanced Materials and Structural Design (8); Passenger Behaviour in Emergency Situations (3); and Passenger Protective Equipment (4). The Technical Evaluation Report and and Addendum are included at the beginning of the Proceedings. Questions and answers of the discussions follow each paper. The last AGARD review on the subject took place in a Specialists' Meeting in 1975, followed by a Working Group Report in 1979 and Lecture Series in 1982. The purpose of the Symposium was a review of the present state-of-the-art and of the last improvements. Although the safety standards in aviation are already very high, there is still room for improvements. They are listed in the Conclusions and Recommendations of the Technical Evaluation Report and in the Addendum.

Book excerpt: Diese Arbeit entstand im Rahmen des Forschungsvorhabens zur statistischen Beschreibung kompressibler turbulenter Scherströmungen mittels einer neuen Methodik. In dieser werden Skalengesetze für die Favre-gemittelten Transportgleichungen für kompressible turbulente Strömungen mittels der Theorie der Lie-, Symmetrie- oder auch Transformationsgruppen bestimmt. Im Wesentlichen umfasst die Arbeit die Erweiterung der Methode der Symmetriegruppen für die inkompressiblen Strömungen auf kompressible Scherströmungen. Der dabei beschrittene Weg basiert auf einer vollständig nicht-linearen Vorgehensweise und läßt sich ausschließlich aus den, die kompressible Strömung beschreibenden Gleichungen, den Navier-Stokes Gleichungen, herleiten. Neue Modellierungshilfen werden aus dem umfangreicheren Satz von Symmetriegruppen für kompressible Strömungen erarbeitet. Weiterhin werden auf der Grundlage der gewonnenen Ergebnisse Turbulenzmodelle validiert und eigene Modellansätze entwickelt. Die Kalibrierung der analytisch ermittelten Gesetze erfolgt anhand von Daten, welche in Direkter Numerischer Simulation (DNS) ermittelt wurden. Dazu wurden kompressible Direkte Numerische Simulationen auf parallelen Großrechnern durchgeführt, welche eine weitere differenzierte Datenbasis für kompressible turbulente Strömungen darstellen. Gruppenparameter, die sich aus den Symmetriemethoden ergeben, werden anhand der numerischen Berechnungen ermittelt. Damit werden die Koeffizienten der Skalengesetze in den turbulenten gemittelten Größen bestimmt. Für die Modellierung stehen somit Skalengesetze mit dem einzig freien, die Kompressibilität beschreibenden Parameter, der Machzahl, zur Verfügung.
