摘要
应用大型商用计算流体力学软件CFX4·3,选用k-ε湍流模型和SI MPLE算法对新钢1200m3高炉考贝式热风炉拱顶空间内烟气分布进行了数值模拟计算.模拟结果表明:悬链线形拱顶比半球形拱顶的烟气分布均匀;在一定范围内,随着悬链线形拱顶高度的增加,在蓄热室横截面上的烟气分布趋于一定程度的均匀.
The large-scale commercial computational fluid dynamics software CFX4.3 was applied to numerically simulate the fume distribution in the top dome of a cowper internal combustion stove of blast furnace with a volume of 1 200 m^3 in XinGang of China. The standard k -ε model and SIMPLE algorithm were used in this simulation. The results show that the hot gas distribution in a catenary dome is evener than that in a hemispheroid dome, and the distribution of hot gas is improved to some extent with the dome height increasing.
