结果表明，湍流控制器可起到减小钢水喷溅、防止二次氧化和改善流体运动路线的作用，并减少短路流的发生。
The results show that turbulence inhibitor has the functions of preventing sputter of liquid steel during casting, avoiding the reoxidation of steel, and decreasing the ratio of short circuit.
计算获得了分离流、二次流和多尺度旋涡结构，表明SST模型能很好地预测尾水管内的湍流流动。
Finally, separation flow, secondary flow and multi-scale eddy structure are simulated, it indicates that SST model can give a good prediction of turbulence in the draft tube.
