摘要
阐述了低温氢的应用前景及泄漏危险性,从气体扩散特性和射流火点火、传播行为两方面介绍了低温氢泄漏的研究现状,对低温氢泄漏气体扩散及射流火传播特性的研究方法、手段及结论进行了总结分析。目前,低温氢泄漏研究方法包括实验研究和数值模拟,多数研究集中在气体扩散特性,对射流火的点火、传播行为的产生条件及影响因素尚不明确。未来应完善低温氢泄漏气体扩散预测模型,以建立有效的低温氢泄漏气体扩散过程及射流火点火、传播预测模型。
The application prospect and risk of leakage are elaborated.The research status on gas diffusion characteristic and jet fire ignition and propagation behavior of cryogenic hydrogen release is reported.The methods and conclusions on gas diffusion and jet flame of cryogenic hydrogen release are summarized and analyzed.The methods include experimental investigation and numerical simulation.Most of the researches focus on the gas diffusion characteristic.The conditions and influencing factors of the ignition and propagation behavior of the jet flame are not yet fully understood.In the future,the prediction model of gas diffusion characteristic during cryogenic hydrogen release should be developed,and the mechanism and influencing factors of cryogenic hydrogen ignition and jet flame propagation behavior should be further studied to establish an effective prediction model on gas diffusion characteristic and jet flame propagation behavior of cryogenic hydrogen release.
