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

2D Shock-Induced Air Bubble Collapse in Water with Open BC

Description

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

Key Challenges for Surrogate Modelling

  • —Accurate interface capturing
  • —Peak pressure in the domain
  • —Understanding wave dynamics
  • —Tracking bubble fragments
