摘要:
文中用CFD技术对甲苯池火灾进行数值模拟,首先对甲苯火焰进行数值计算,得到在稳定的横向风条件下,甲苯燃烧的峰温、产物组分、瞬时速度等火焰特征参数以及其空间分布情况:火焰温度的最高点在对称面y=0上,最高温度为1778K,火焰倾斜角度为26°(与竖直方向夹角),火焰高为22.5m。然后应用CFD软件F luent对池火灾进行热辐射模拟,模拟结果表明:对于锰钢材料、内径为20m甲苯储罐,稳态有风池火灾情况下,相邻两储罐之间安全距离在上风向为59m,下风向为72m。由于描述燃烧过程和湍流情况的数学物理模型还不太完善、对大气状况的简化等原因,结果偏保守,文中对此进行了分析讨论。此项研究为CFD技术研究碳氢化合物火灾的一个尝试。
Abstract:
Take the benzene for example, a matter with hazardous character belongs to first grade, a pool fire of it with cross wind was simulated based on CFD technology. First, the flame character of the pool fire, e.g. the burning temperature, product of combustion, instantaneous velocity and so on was calculated, and the space distribution of all of the characters were simulated: the maximum temperature of the fire is 1778K and is on the symmetry plane y=0, the incline angle of the fire is 26?(reference the y-axis), the height of the fire is 22.5m. And then, the heat radiation of the steady pool fire was numerically simulated by CFD software, fluent. The result showed that under steady state pool fire with cross wind, the minimum safety distance between two tanks made of manganese steel with a diameter of 20m is 59m up the wind direction and 72m down the wind direction. The simulate results was analyzed at last in the paper. The simulation calculation was obviously conservative, which was ascribed to the faulty mathematical models, used for describe the process of combustion and overfall condition, and the simplification of the atmospheric condition, which was discussed in the paper. The study was a attempt of using CFD technology to study hydrocarbon fire.
