Zusammenfassung

In einer Dampfturbine erfolgt die Umwandlung von potentieller Energie in mechanische Energie auf indirektem Weg über die kinetische Energie des Arbeitsmittels. Daraus folgt, dass für die rechnerische Beschreibung der Energieumsetzung Strömungsvorgänge von entscheidender Bedeutung sind. Gerade im Bereich der Strömungen haben in den letzten Jahren rechnergestützte Verfahren eine stürmische Entwicklung erfahren. Numerische Verfahren zur Berechnung von dreidimensionalen Strömungen (CFD = Computational Fluid Dynamics) werden heute im Auslegungs- und Entwicklungsprozess von Dampfturbinen zunehmend eingesetzt. Trotzdem bilden einfachere null-, ein- und zweidimensionale rechnergestützte Berechnungsverfahren nach wie vor das Rückgrat bei der Auslegung von Dampfturbinen. In diesem Kapitel werden die Methoden und ihre Grundlagen kurz beschrieben und es werden Beispiele für deren Anwendung im Bereich der Auslegung und Entwicklung von Dampfturbinen gegeben.
