Abstract: The inertia dominated collapse of micro cavitation bubbles in a viscous liquid with surface tension is investigated. In addition to the well known dramatic collapse mode, a smooth decrease of the void cavity is also possible due to the viscous damping. This effect is especially important for micro bubbles although the importance of surface tension increases strongly with decreasing initial radius. The collapse discussion can be performed easily without large numerical efforts by means of an analytical collapse criterion formulated by Bogoyavlenskiy. The results presented are relevant for cavitation theory and particular helpful for applications in microfluidic systems. |
