Cavitation Inside Droplets Induced by Shocks

Abstract

We simulate the interactions of a water droplet and shock wave, focusing on early stages as the internally reflected
waves decrease the droplet minimum pressure and can induce cavitation, thereby latering the breakup process.
Results show how the minimum pressure evolve and is affected by the presence of a small air cavity, significantly
decreasing the its magnitude. By the final abstract deadline, the authors expect to include simulations in which
phase-change is activated such that regions of water vapor are generated as a consequence of the minimum pressure
being below the cavitation threshold.
