| 摘 要： | 针对直流电弧炉冶炼过程,在二维近似条件下,利用PHOENICS程序对直流电弧炉内电弧射流的磁流体力学模型进行了数值模拟,分析了电势法和磁场法在电弧射流数值模拟研究中的异同,并将这两种方法的计算结果与已有的实验结果进行了比较.结果表明,磁场法的计算结果高于电势法且与实验结果更加接近;但从数值模拟的角度看,电势法更易实现.

| Abstract: | A two-dimensional magnetohydrodynamic model which is used to describe the arc plasma of DC electric arc furnace was presented and solved by PHOENICS software. A comparison of arc plasma numerical simulation was made between potential approach and magnetic approach. Calculated results were compared with the experimental measurements reported in other article, it is showed that the calculated results of magnetic approach are higher than that of potential approach and agree better with the measured results. However, potential approach is a more convenient and numerically better-behaved method to represent the arc plasma from the numerical simulation point of view. |
