Projektbeschreibung

Die effiziente Nutzung verfügbarer Energie ist eine der großen Herausforderungen unserer Zeit. Eine besondere Bedeutung kommt dabei der Analyse und Optimierung von Formen und Strukturen hinsichtlich ihrer aerodynamischen Eigenschaften zu. Wichtige Anwendungsgebiete sind die Entwicklung energieeffizienter Fahrzeuge und die Windenergietechnik.

Rechnergestützte Ansätze durch Simulation und automatische Optimierung sind heute selbstverständlicher Teil der technischen Entwicklung und haben zu erheblichen Verbesserungen geführt. Die hohe Komplexität sowohl hinsichtlich
der Rechenzeit als auch bezüglich des Speicherbedarfs limitiert jedoch bislang solche Ansätze. Zusammen mit unseren Forschungs- und Entwicklungspartnern bauen wir auf bewährten Ansätzen der Datenreduktion und der Surrogatmodellierung auf, um dieses Problem signifikant zu verkleinern:

Durch Kombination mit indirekten Oberflächencodierungen werden neue Methoden entwickelt um einen erheblichen Teil der Simulationen einzusparen und so komplexere Anwendungsfragestellungen zu lösen.
Mit einer komponentenbasierten Architektur und der Weiterentwicklung zugrundeliegender Softwaremethoden wird vermieden, dass die Kombination unterschiedlicher Verfahren durch Implementierungsaspekte oder Qualitätseinbußen limitiert wird.

Dies unterstreicht die Einsatzmöglichkeiten dieser neuen Technologie und ermöglicht weitreichende Verbesserungen in diesen gesellschaftlich bedeutsamen Anwendungsgebieten.
