摘　　要：计算机模拟方法是当今研究油罐火灾发生、发展规律的重要手段。为此 ,从油罐燃烧的特点出发 ,搜集了当前最新的 1 7种火灾模型 ,对比分析了它们的特点和适用范围 ,并筛选出 7种适于模拟油罐火灾的模型 :ALOFT -FT ,FDS ,CFX ,FLUENT ,PHOENICS ,JASMINE和FIRE。通过对这些模型计算方法的进一步比较 ,分析了利用这 7种模型模拟油罐火灾的优点和缺点。最后 ,提出了运用FDS模型模拟油罐火灾的优势 ,并用其进行了计算和分析 。Numerical simulation is an important method for investigating the regularity of oil tank fire from the very beginning to the end. Based on the characteristics o f oil tank fires, 17 latest fire models are collected. By comparing the characte ristics and application of these models, seven models that could be applied to s imulate the oil tank fires are chosen,i.e. ALOFT-FT, FDS, CFX, FLUENT, PHOENIC S, JASMINE and FIRE. Then the calculation methods of these models are further an alyzed to find the advantages and disadvantages of each own when used in simulat ing oil tank fires. Finally,it concludes that FDS has more advantages than othe rs with satisfactory results.
