多参数影响的时-空-浓度多维度的氢气泄漏特征仿真数据集

针对氢气泄漏空间维度复杂，泄漏模拟计算不稳定，单一CFD模型计算精确度低、速度慢等问题，本项目结合理论模型采用多阶段CFD模方法建立氢气泄漏数值模型，测量在不同通风条件下、障碍物条件下、泄漏条件下泄漏气体分布情况，获得1%、4%浓度等值面以及空间监测线的浓度变化值。

To address the problems including complex spatial dimensions of hydrogen leakage, unstable computational performance of leakage simulations, low accuracy and slow computation speed of single CFD models, this project establishes a numerical model for hydrogen leakage via a multi-stage CFD modeling approach combined with theoretical frameworks. We measure the distribution of leaked gas under varying ventilation conditions, obstacle configurations and leakage scenarios, and acquire the 1% and 4% concentration isosurfaces as well as the concentration variation data collected from spatial monitoring lines.
