Zusammenfassung

Es wird die Grenzschicht an einem abgestumpften Keil mit Hilfe der Görtlerschen Reihe berechnet. Man findet, von der Staupunkt-Grenzschicht ausgehend, eine asymptotische Annäherung an die Grenzschichten von Falkner und Skan; die asymptotische Lösung wird mit Hilfe der Reihe sehr befriedigend dargestellt, besonders nach Anwendung von verschiedenen Methoden zur Verbesserung der Konvergenz. Zudem wird die Annäherung an die Lösung im Unendlichen analytisch untersucht, wobei sogenannte asymptotische Eigenfunktionen auftreten.

Die rechnerisch ausgewertete Lösung für einen Keil mit rechteckigem Öffnungswinkel kann als Vergleichsfall zur Beurteilung von numerischen Methoden benützt werden.
