隧道空间氢燃料电池汽车射流火焰特性研究
Study on the Jet Flame Characteristics of Hydrogen Fuel Cell Vehicle in Tunnel Space
摘要
Abstract
With the increasingly serious problems of global climate change and environmental pollution,hy-drogen fuel cell vehicles,which have advantages such as zero carbon,high efficiency and renewability,have re-ceived extensive attention and rapid development.To explore the flame characteristics of jet fire induced by leakage of hydrogen fuel cell vehicles in tunnel space,taking hydrogen fuel cell vehicles in tunnels as the re-search object,numerical simulation based on Fluent software was adopted.By modeling hydrogen fuel cell vehi-cles in tunnels and conducting grid division,the differences in jet flame behavior of hydrogen fuel cell vehicles in tunnel space under different leakage pressures were explored.The characteristic parameters such as the flame behavior of hydrogen jets in different directions and the flame temperature distribution after the jet fire strikes the tunnel wall surface were analyzed.The results showed that the length and width of the hydrogen jet flame in-creased with the increase of leakage pressure,the flame temperature increased with the increase of leakage pres-sure,and the temperature of the jet flame axis showed a trend of increasing first and then decreasing with the in-crease of distance.The research provided a reference for the safe application of hydrogen fuel cell vehicles in tunnel scenarios and contributed to the application and promotion of the hydrogen fuel cell vehicle industry.关键词
