Mutual interaction of a collapsing bubble and a nearby viscoelastic solid

This work investigates the interaction of a viscoelastic solid and a nearby collapsing bubble, using numerical simulations. The Deborah number, which quantifies the relative time scales of solid deformation and bubble dynamics, is found to effectively characterize the bubble-solid interaction. Analyses on the temporal distribution of energy components and the imbalance in pressure distribution surrounding the bubble reveal the rationale behind changes in bubble behaviors with respect to the viscosity and elasticity of the solid. Furthermore, the solid deformation induced by an expanding and collapsing bubble and the shape of the crater formed by a bubble jet are examined.
