摘要
气泡浮力是促使钢包产生钢液循环的驱动力,正确理解吹气钢包内气液两相区结构是开展模拟研究的关键。分析了钢包内两相区的含气率模型,依靠对商业软件FLUENT的二次开发,将该模型引入特定钢包进行计算。在本计算条件下,认为数学计算模型与实际两相区结构比较相符,能够反映吹气钢包内流体流动的实际情况。
The bubble buoyancy is the driving force to promote molten steel circulation in ladle. The key of physical and numerical simulation is to correctly understand the structure of gas-liquid region in ladle. In this paper, on the basis of analyzing on two-phase region model, it is calculated in a special ladle by secondary development of commercial software FLUENT. The numerical results show that the gas-liquid model is close to actual experiences and can reflect the real fluid flow condition in ladle.
