On the pair correlation function in a bubble swarm
-
C. Santarelli
Abstract
The paper presents results on the dynamics of bubbles in a mono- and in a bi-disperse bubble swarm. The radial pair correlation function provides insight into the characteristic bubble clustering length. The angular pair correlation function shows that for small distances the most probable alignment of a bubble pair is horizontal.
Kurzfassung
Der Beitrag enthält Ergebnisse zur Blasendynamik in einem mono- und bi-dispersen Blasenschwarm. Die radiale Paarkorrelationsfunktion liefert Informationen über die charakteristische Größe von Blasencluster. Die Winkel-Paarkorrelationsfunktion zeigt, dass für kleine Abstände die wahrscheinlichste Ausrichtung eines Blasenpaares die horizontale ist.
