3D Shock-Induced Air Bubble Collapse in Water

Description

The dataset captures the time-evolving behavior of 3D spherical 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 symmetric boundary conditions at the north, south, top and bottom walls.

Dataset Structure

The train.h5 and test.h5 in this repository are meta hdf5 files that link to multiple subparts inside the corresponding subset folder. The mentioned train-test-split [0.8 - 0.2] is only valid when all subparts inside the subset folder are present.

Key Challenges for Surrogate Modelling

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