Investigations of Laser-Induced Cavitation Bubble Oscillation in Glycerol-Water Mixture

The effect of bubble content on cavitation bubble oscillation in glycerol-water mixture is investigated by the fiber-optical detection sensor based on the beam deflection principle in combination with theoretical analysis. The result indicates that the bubble content has an obvious influence on bubble oscillation. The maximum bubble radii and oscillation cycle at each oscillating cycle in different viscous fluid increase with bubble content. In the meantime, the relationship of the velocity of bubble wall vary with bubble content are also given in this paper. In addition, influenced by the liquid viscosity, the process of bubble expansion and shrinking velocity slow down.
