摘　　要：采用计算机模拟的方法,对闪速炼铅炉进行了气粒两相流场、温度场、浓度场等多个物理场耦合模拟,着重研究炉内速度场的特性。采用传统的二维截面速度矢量图分析了两组截面的速度场,发现其对速度场信息描述不完整,而且难以对不同截面上速度矢量分布之间相互联系进行分析。借助可视化软件ParaView,提出了将立体流线、方向标识体和动画结合起来制作流线动画,对整个速度场进行分析,使问题得到有效改善。分析发现右侧喷嘴主流触底后斜向上喷射是影响速度场分布的重要原因。Using computer simulation method, the gas-particle two-phase flow field, temperature field and concentration field of lead flash smelting furnace were simulated. The characteristics of the velocity field in the furnace were focused on. With the traditional two-dimensional cross-sectional velocity vector, the velocity field in two sets of cross-section was analyzed. However, with this method, the velocity field could not be described completely and it was difficult to analyze the relationship of velocity vector in different cross-section. With the visualization software ParaView, the three-dimensional flow line, the direction indicator body and animation were combined to make the animation of flow line, which was used to analyze the whole velocity field. By the animation, the above-mentioned problems could be improved effectively . It was found that the phenomenon that the mainstream of right nozzle hit the bottom and then jetted obliquely was a deep-seated important reason which affected the velocity field distribution.
