Abstract
Ein Prinzipexperiment im DLR Projekt VicToria dient der Analyse von Strömungsphänomenen, die nahe der Pumpgrenze in Turboverdichtern auftreten. Durch die hervorragende optische Zugänglichkeit des Diffusors wird die direkte Bewertung der Wiedergabe von 3D Ablösungen und Wirbeln durch Reynolds-Averaged Navier-Stokes Simulationen ermöglicht. Dabei werden differentielle Reynoldsspannungsmodelle mit verschiedenen Erweiterungen für Strömungen mit adversen Druckgradienten untersucht und bewertet.
