时-空-浓度多维度的氢气泄漏特征可视化数据集

针对燃料电池汽车使用过程中电堆与基础设施氢气安全测试及监控技术提升的需求，在实验层面研究开发了可视化测量氢气射流浓度场的实验方案，对不同实验条件下的氢气泄漏进行浓度场测量，通过纹影可视化图像采集系统，对不同压力、流量和喷嘴直径的氢泄漏模拟实验的动态图像进行高速摄像采集，最终获得经过灰度化处理的成组512×512像素射流图像

Aiming at enhancing hydrogen safety testing and monitoring technologies for fuel cell stacks and supporting infrastructure during the operation of fuel cell vehicles, this research developed an experimental protocol for visual measurement of hydrogen jet concentration fields. Concentration field measurements of hydrogen leakage events were performed under various experimental conditions. Leveraging a schlieren visualization image acquisition system, high-speed photography was employed to collect dynamic images from hydrogen leakage simulation experiments with varying pressures, flow rates and nozzle diameters. Ultimately, a set of grayscaled jet images with a resolution of 512×512 pixels were obtained.
