2D Shock-Induced R22 Bubble Collapse in Air
Description
The dataset captures the time-evolving behavior of 2D cylindrical R22 bubbles subjected to an external shock wave in air. The interaction with the shock wave results in a collapse of the R22 bubble. Here we investigate a scenario with open boundary conditions at every wall.
