摘要： 从高炉出铁口中射出的铁水具有一定的初动能，且出铁沟有一定的坡度.本项目提出了一种利用高炉出铁沟重力势能脱硫的新型冶金反应器.基于湍流模型与多相流模型的耦合，应用液面追踪技术，实现了对冶金重力势能反应器内流体流动及液面波动行为的模拟计算，并用水模拟结果进行了对比验证.从分析的结果来看，铁水在反应器内能够形成良好的旋流效果.实验所得的RTD曲线与计算所得的结果吻合较好.碗型反应器的旋流效果最好，能够产生高强度稳定的旋流.

Abstract: The jet-flow of hot metal from the blast furnace has a certain initial kinetic energy. In addition， the tapping channel has a certain degree of slope. An innovative metallurgical reactor using the gravitational potential energy of the hot metal was proposed. On the basis of turbulent model and multiphase flow model， the fluid flow and the free-surface shape with VOF (volume of fluid) model in metallurgical reactor was numerically simulated， which was verified by the water model. The results show that the best swirling flow is formed in the bowl-shape reactor compared with other shapes. The curve of residence time distribution (RTD) obtained from experiment is in good agreement with the simulated result. The effect of swirling flow in bowl-shape reactor is greater than the others， which produces the most intensive and stable swirling flow.

Key words: gravitational potential energy, stirring characteristics, metallurgical reactor, numerical simulation
