储罐池火特性研究进展

Research Progress on Fire Characteristics of Storage Tanks

总结了常见池火特性参数如燃烧速率、火焰形态、火焰脉动、热辐射通量的半经验公式,计算得出燃烧速率、火焰拖曳直径、火焰脉动随储罐直径变化规律,火焰倾角随风速变化规律,热辐射通量随距离的变化规律,确定了多个公式的适用范围,指出了多个特性参数存在的问题,并提出了未来的研究方向。

This paper summarized the classical theory and semi empirical formula of common pool fire characteristic parameters such as the burning rate,the flame temperature,flame shape,flame pulsation,and thermal flux.Calculation was performed to study how the burning rate,the flame height,flame drag diameter,and flame pulsation changed with tank diameter,how the flame angle changed with wind speed and how thermal flux changed with the distance.The scope of application,the existing problems of various characteristic,as well as future research directions were put forward.
