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. <div style="display:flex;justify-content:center"> <video style="width:100%;max-width:400px" src="https://huggingface.co/datasets/FluidVerse/2D_SABW_OOOO/resolve/main/SABW_OOOO_Mas2.10.mp4" loop autoplay muted></video> </div> ## About the data |Metadata|Description| |-----|------| |Solver|[ALPACA](https://www.sciencedirect.com/science/article/abs/pii/S0010465521003581)| |PDE|2D compressible Euler equations| |Dimension|2D| |Number of Trajectories|300| |Train-Test-Split|0.8 - 0.2| |Number of Timesteps|101| |Simulation End Time|15 \\( \mu s \\)| |Save Interval|0.15 \\( \mu s \\)| |Fields| - density_mixed <br/> - density_water <br/> - density_air <br/> - pressure <br/> - velocityX <br/> - velocityY <br/> - volume_fraction_water| |Simulation Resolution|2048x2560 (Clipped and Downsampled)| |Dataset Resolution|512x512 & 256x256| |Grid Type|Cartesian Uniform Grid| |Initial Condition|The bubbles are in equilibrium with the surrounding pre-shock environment.| |Boundary Conditions| North: Open <br/> South: Open <br/> East: Open <br/> West: Open| |Conditioning Parameters| Shock Mach Number [1.3 - 2.1] <br/> Bubble Count [1 - 5] <br/> Bubble Radius [2mm - 3.5mm] <br/> Bubble Center Position [Random in Domain] Further metadata information can be found in the corresponding `metadata.json` file. ## Key Challenges for Surrogate Modelling - Accurate interface capturing - Peak pressure in the domain - Understanding wave dynamics - Tracking bubble fragments ## How to Download the Dataset Download the whole dataset: ``` hf download FluidVerse/2D_SABW_OOOO --repo-type dataset ``` Download only part of the dataset with resolution 256x256: ``` from huggingface_hub import snapshot_download snapshot_download( repo_id="FluidVerse/2D_SABW_OOOO", repo_type="dataset", allow_patterns="multi_bubble/256x256/*", local_dir="." ) ```
