摘　　要：采用数学模拟的地方法研究了不同型号的布流系统对双辊薄带熔池内流体流动和液面波动的影响.使用Fluent软件的VOF多相流模型对I号和III号布流系统进行了数学模拟,并同水力学模拟的结果进行了对比,研究结果表明,VOF模型符合水力学模拟实验结果;III号布流系统比I号布流系统的布流效果更好,流态稳定,液面波动明显减小.Numerical simulation was carried out to investigate flow patterns in the pool of water model of twin-roll strip caster.The influences of configurations of different delivery systems on flow pattern and surface fluctuation in the pool were analyzed.The VOF multiphase flow model involved in the Fluent software was used to simulate the two different metal delivery systems of No.1 and No.3.It was found that the results of VOF model agreed with the hydraulic results.The No.3 delivery system had more stable flow and less surface fluctuation than that in No.1,thus the delivery effect of No.3 delivery system was better than that of No.I.
