Abstract

Es wird die Bewegung eines kleinen spharischen Teilchens in einer Couette-Stromung untersucht. Wenn die Reynolds-Zahl grosser ist als ein kritischer Wert, so wird die Teilchen-Bewegung in laminarer Stromung instabil und verursacht Turbulenz; unterhalb des kritischen Wertes bleibt die Stromung laminar. Die kritische Reynolds-Zahl (auf Teilchen-Durchmesser und Geschwindigkeitsgradient basierend) hangt nur vom Dichteverhaltnis zwischen der Flussigkeit und der Kugelab.
