Numerical Simulation of Bubble Deformation and Breakage Under Shock Waves
To study the interaction between shock waves and bubbles and understand the cause and mechanism of bubble deformation and breakage induced by shock waves,CFD numerical simulation is used to study the deformation and breakage of single bubbles under the action of shock waves,and VOF multiphase flow model is used to capture the bub-ble interface in this paper.The simulated bubble morphology is in good agreement with the literature results.The results show that the upper vertex of the bubble generates a downward microjet,and the bubble interface generates vorticity.The bubble changes from spherical to heart-shaped to funnel-shaped,and finally the bubble breaks.
