| 摘 要： | 应用边界适体坐标（ＢＦＣ）技术计算底吹钢包内的三维流场，该计算无需在未知流场内设置内边界，而使流动及运动的合金可顺利跨越圆心轴。在计算合金运动轨迹时，修正了合金在气液两相区内运动模型的参数。最后分析了若干因素对合金运动轨迹的影响。

| Abstract: | The internal boundary in flow field, which must be designated in the cylindrical polar coodinate system, can be avoided by using body-fitted coordinate system (BFC). Consequently, computed flow of molten steel and paths of alloying additions are able to cross smoothly the geometric centerline of cylindrical verssel.Motion of particles is calculated in three dimensional coordinate system, the modification of parameters,such as the drag coefficient and density in the two phase region, is examined. Some factors affecting the trajectories of alloying additions are discussed. |
