收藏资源简介:
该数据集捕捉了在空气中受到外部冲击波的二维圆柱形液滴的时间演化行为。与冲击波的相互作用导致两种不同的破碎模式,即SIE和RTP,具体取决于韦伯数。本研究调查了在南北壁对称边界条件下的情景。数据集包含300条轨迹,训练-测试分割比为0.8 - 0.2,每条轨迹有101个时间步长。模拟结束时间为91微秒至1240微秒(取决于初始条件),保存间隔为0.91微秒至12.40微秒。数据集包含多个字段,如混合密度、水密度、空气密度、压力、速度X、速度Y和水的体积分数。模拟分辨率为1024x512(经过裁剪和下采样),数据集分辨率为512x512和256x256。网格类型为笛卡尔均匀网格。初始条件为液滴与周围预冲击环境处于平衡状态。边界条件为北和南对称,东和西开放。条件参数包括冲击马赫数(1.2 - 3.2)、韦伯数(10 - 30及10k - 30k)、液滴数量(1 - 5)、液滴半径(2mm - 3.5mm)和液滴中心位置(在域内随机)。该数据集适用于研究冲击诱导液滴破碎、界面捕获、波动力学、液滴碎片追踪以及多液滴相互作用等科学机器学习任务。
This dataset captures the temporal evolution of 2D cylindrical liquid droplets subjected to external shock waves in air. The interaction between the droplets and shock waves induces two distinct breakup modes, namely SIE and RTP, which depend on the Weber number. This study investigates scenarios with symmetric boundary conditions on the north and south walls. The dataset contains 300 trajectories, with a train-test split ratio of 0.8:0.2, and each trajectory has 101 time steps. The simulation end times range from 91 μs to 1240 μs (depending on initial conditions), with a saving interval of 0.91 μs to 12.40 μs. The dataset includes multiple fields, such as mixture density, water density, air density, pressure, velocity X, velocity Y, and water volume fraction. The simulation resolution is 1024×512 (after cropping and downsampling), while the dataset resolutions are 512×512 and 256×256. The grid adopts uniform Cartesian grids. The initial condition is that the liquid droplets are in equilibrium with the surrounding pre-shock environment. The boundary conditions are symmetric on the north and south, and open on the east and west. The conditional parameters include shock Mach number (1.2–3.2), Weber number (10–30 and 10k–30k), number of liquid droplets (1–5), droplet radius (2 mm–3.5 mm), and droplet center position (random within the domain). This dataset is applicable to scientific machine learning tasks such as shock-induced droplet breakup, interface trapping, wave dynamics, droplet fragment tracking, and multi-droplet interactions.
