Research progress of hydrogen safety modeling
摘要
Abstract
Hydrogen energy is critical to the realization of national dual-carbon goals.Due to the unique properties,hydrogen is extremely vulnerable to leakage during storage,transportation and use,which can lead to serious accidents and has become one of the major obstacles to the large-scale application of hydrogen energy.To address the safety challenges in the utilization of hydrogen energy,it is crucial to conduct risk studies.This paper briefly introduces the basic properties of hydrogen,discusses the numerical modeling methods of hydrogen and liquid hydrogen leakage,dispersion,jet flame and explosion,summarizes the evolution laws and internal mechanisms of hydrogen and liquid hydrogen in the processes of leakage,diffusion,jet combustion and explosion,deeply analyzes the key factors affecting the above processes,such as the gas type,storage conditions,leakage conditions,environmental conditions,ventilation conditions,etc.,and focuses on the application of computational fluid dynamics(CFD)method in the current research.It points out the shortcomings of current research and provides suggestions for future development directions,which are of guiding significance to promote the research on hydrogen safety and improve the accident prevention and emergency response mechanism.关键词
