BubbleSH
收藏资源简介:
BubbleSH是由埃因霍温理工大学创建的高保真气泡流数据集,专注于捕捉可变形气泡在群体中的瞬态三维动力学行为。该数据集源自高分辨率前向追踪直接数值模拟,包含24种参数配置下32个气泡的时间序列数据,每个气泡通过球谐系数紧凑表征其形态演化,实现了约173倍的压缩比,有效融合了轨迹运动与表面几何的耦合信息。其生成过程基于精确的界面解析数值方法,通过周期性边界条件模拟了空气-水系统中气泡群的上升过程。该数据集旨在为数据驱动的多相流模拟器开发提供基准,特别适用于几何深度学习模型在可变形物体与湍流交互场景中的训练与评估,以解决传统欧拉-拉格朗日模型中因平均化导致的气泡变异性与瞬态变形信息丢失问题。
BubbleSH is a high-fidelity bubbly flow dataset developed by Eindhoven University of Technology, focusing on capturing the transient 3D dynamical behaviors of deformable bubbles in a bubble swarm. This dataset is derived from high-resolution forward-tracking direct numerical simulations, containing time-series data of 32 bubbles under 24 distinct parameter configurations. The morphological evolution of each bubble is compactly represented via spherical harmonic coefficients, achieving an approximately 173-fold compression ratio that effectively fuses the coupled information between trajectory motion and surface geometry. Its generation process relies on an accurate interface-resolved numerical method, which simulates the rising dynamics of bubble swarms in an air-water system using periodic boundary conditions. This dataset aims to serve as a benchmark for the development of data-driven multiphase flow simulators, and is particularly well-suited for training and evaluating geometric deep learning models in scenarios involving deformable objects interacting with turbulence, to address the loss of bubble variability and transient deformation information caused by averaging in traditional Euler-Lagrange models.
