000013900 520__ $$2eng$$aUnderstanding the dynamics of cavitation bubbles and the shock waves emitted by their collapse in and near viscoelastic media is important for various naval and medical applications, particularly in the context of cavitation damage. Although not fully understood, the damage mechanism combines the effect of the incoming pulses and cavitation produced by the high tension. Additionally, the influence of the shock on the material and the response of the material to the shock are not well known. A novel Eulerian numerical method for simulating shock and acoustic wave propagation in a Zener-like viscoelastic media is leveraged. The method is high-order accurate, solution-adaptive and based on a weighted essentially non-oscillatory scheme for shock capturing. Validation results and studies for two-dimensional simulations of the bubble collapse dynamics will be presented. Three-dimensional studies of the bubble collapse dynamics for various experimental studies of viscous and viscoelastic media will also be presented.
