该数据集捕捉了二维圆柱形空气泡在水中受外部冲击波作用的时间演化行为。冲击波的相互作用导致空气泡坍塌。本研究采用四周开放边界条件的情景。数据集包含300条轨迹,每条轨迹有101个时间步长,模拟结束时间为15微秒,保存间隔为0.15微秒。数据字段包括混合密度、水密度、空气密度、压力、X/Y方向速度和水体积分数。模拟分辨率为2048x2560(经过裁剪和下采样),数据集提供512x512和256x256两种分辨率。数据采用笛卡尔均匀网格,初始条件为气泡与周围预冲击环境处于平衡状态。边界条件为四周开放。关键建模挑战包括准确界面捕捉、域内峰值压力、理解波动力学和追踪气泡碎片。数据集适用于计算流体力学(CFD)、多相流、可压缩流和科学机器学习(SciML)等领域的研究。
This dataset captures the temporal evolution of two-dimensional cylindrical air bubbles in water under external shock wave loading. The interaction of these shock waves induces the collapse of the air bubbles. This study utilizes a computational setup with four open boundary conditions. The dataset contains 300 trajectories, each with 101 time steps. The simulation concludes at 15 microseconds, with a data saving interval of 0.15 microseconds. The data fields include mixture density, water density, air density, pressure, velocities in X and Y directions, and water volume fraction. The original simulation resolution is 2048×2560 after cropping and downsampling, and the dataset provides two accessible resolutions: 512×512 and 256×256. The data is generated on a Cartesian uniform grid, with initial conditions where the air bubble is in equilibrium with the surrounding pre-shock environment. Key modeling challenges in this work include accurate interface capturing, prediction of intra-domain peak pressures, understanding of wave dynamics, and tracking of bubble fragments. This dataset is suitable for research in fields such as computational fluid dynamics (CFD), multiphase flow, compressible flow, and scientific machine learning (SciML).
