Abstract
A clarification of the effect of polymers on cavitation phenomena is an important and interesting subject in the field of fluid dynamics. In the present paper, the behavior of cavity clusters in polymer aqueous solutions subjected to an ultrasonic oscillation are studied. The validity of the model of bubble cluster dynamics in Newtonian fluids, proposed by Hansson and Mørch, is examined by observation of a cavity cluster in a polymer solution. Secondly, the motions of cavity cluster in non-Newtonian fluids are theoretically analysed. According to numerical calculations, the effects of the amplitude and frequency of the oscillating pressure on the collapsing process of the clusters in a polymer solution are made clear.
