摘要
针对高炉炼铁的复杂过程,基于计算流体动力学(CFD:ComputationalFluidDynamics)技术建立一种二维数学模型,模拟了多相流在高炉中运动及热传递情况。模型中包括气、液、颗粒和粉四种相态,并对高炉中存在的主要化学反应做了简化处理。其充分考虑了各个相态之间的耦合作用,分析它们之间相互关系,因此能够预测当一种相态参数变化时,其它各相产生的相应变化。应用所建模型计算得到了各个相态的稳态速度、温度等结果,尤其可仿真软熔带、回旋区等关键区域的情况,为高炉仿真做了很有意义的尝试,也为指导高炉运行提供了新的方法。
Based on the CFD（Computational Fluid Dynamics） technology, a two dimensional mathematical model of the blast furnace （BF） was built to simulate ironmaking process, meanwhile the m ultiphase fluid motion and heat transfer were considered. Phase of gas, liquid, particle and fine were included in this model, as well as simple chemical reactions. The model considered the coupling relationships of phases, so every phase could change as the changes of other phase characters. The steady velocity and temperature of per-phase described by numerical calculation are very important for BF, especially the simulation results of cohesive zone and raceway. The theory and model built here provided a helpful try for BF simulation and a new method for guidance on BF operation.
