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. <div style="display:flex;justify-content:center"> <video style="width:100%;max-width:800px" src="https://huggingface.co/datasets/FluidVerse/3D_SABW_SSOOSS/resolve/main/3D_SABW_SSOOSS_Mas1.30.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|3D| |Number of Trajectories|180| |Train-Test-Split|0.8 - 0.2| |Number of Timesteps|51| |Simulation End Time|15 \\( \mu s \\)| |Save Interval|0.3 \\( \mu s \\)| |Fields| - density_mixed <br/> - density_water <br/> - density_air <br/> - pressure <br/> - velocityX <br/> - velocityY <br/> - velocityZ <br/> - volume_fraction_water| |Simulation Resolution|512x256x256 (Clipped and Downsampled)| |Dataset Resolution|256x256x256 & 128x128x128| |Grid Type|Cartesian Uniform Grid| |Initial Condition|The bubbles are in equilibrium with the surrounding pre-shock environment.| |Boundary Conditions| North: Symmetry <br/> South: Symmetry <br/> Top: Symmetry <br/> Bottom: Symmetry <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. ## 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 ## How to Download the Dataset Download the whole dataset: ``` hf download FluidVerse/3D_SABW_SSOOSS --repo-type dataset ``` Download only part of the dataset with resolution 128x128x128: ``` from huggingface_hub import snapshot_download snapshot_download( repo_id="FluidVerse/3D_SABW_SSOOSS", repo_type="dataset", allow_patterns="3d_shock_multi_air_bubble_collapse_in_water/128x128x128/*", local_dir="." ) ```--- license: 知识共享署名-非商业性使用4.0（CC BY-NC 4.0） tags: - 计算流体动力学（Computational Fluid Dynamics, CFD） - 多相流（Multiphase） - 可压缩流动（CompressibleFlow） - 科学机器学习（Scientific Machine Learning, SciML） - 气泡（Bubbles） - 激波（Shock） - 三维（3D） pretty_name: 水中激波诱导的三维空气气泡溃灭 size_categories: - 1000 < n < 10000 --- # 水中激波诱导的三维空气气泡溃灭 ## 数据集说明 本数据集记录了水中受外部激波作用的三维球形空气气泡的时间演化行为。气泡与激波相互作用后会发生溃灭，本研究针对北、南、顶、底壁面采用对称边界条件的场景展开分析。 <div style="display:flex;justify-content:center"> <video style="width:100%;max-width:800px" src="https://huggingface.co/datasets/FluidVerse/3D_SABW_SSOOSS/resolve/main/3D_SABW_SSOOSS_Mas1.30.mp4" loop autoplay muted></video> </div> ## 数据详情 |元数据|描述| |-----|------| |求解器|[ALPACA](https://www.sciencedirect.com/science/article/abs/pii/S0010465521003581)| |偏微分方程（Partial Differential Equation, PDE）|二维可压缩欧拉方程| |维度|三维| |轨迹数量|180| |训练测试划分比|0.8 - 0.2| |时间步数量|51| |模拟终止时间|15 μs（微秒）| |保存间隔|0.3 μs（微秒）| |数据场| - 混合密度（density_mixed）<br/> - 水密度（density_water）<br/> - 空气密度（density_air）<br/> - 压强（pressure）<br/> - X方向速度（velocityX）<br/> - Y方向速度（velocityY）<br/> - Z方向速度（velocityZ）<br/> - 水体积分数（volume_fraction_water）| |模拟分辨率|512×256×256（经裁剪与降采样处理）| |数据集分辨率|256×256×256 与 128×128×128| |网格类型|笛卡尔均匀网格| |初始条件|气泡与周围激波前环境处于平衡状态| |边界条件| 北：对称边界 <br/> 南：对称边界 <br/> 顶：对称边界 <br/> 底：对称边界 <br/> 东：开放边界 <br/> 西：开放边界| |调控参数| 激波马赫数：1.3 - 2.1 <br/> 气泡数量：1 - 5 <br/> 气泡半径：2mm - 3.5mm <br/> 气泡中心位置：域内随机分布| 更多元数据信息可参阅对应`metadata.json`文件。 ## 数据集结构 本仓库中的train.h5与test.h5为元HDF5文件，用于链接对应子集文件夹内的多个子部分。上述训练测试划分比0.8-0.2仅在子集文件夹内所有子部分均完整存在时生效。 ## 代理建模核心挑战 - 精准的界面捕捉 - 域内峰值压强预测 - 波动动力学机制解析 - 气泡碎片追踪 ## 数据集下载方式 完整下载数据集： hf download FluidVerse/3D_SABW_SSOOSS --repo-type dataset 仅下载分辨率为128×128×128的数据集子集： from huggingface_hub import snapshot_download snapshot_download( repo_id="FluidVerse/3D_SABW_SSOOSS", repo_type="dataset", allow_patterns="3d_shock_multi_air_bubble_collapse_in_water/128x128x128/*", local_dir="." )
