应用矢量流函数－涡量（φ－Ω）法，采用Ｋ－ε双方程湍流模型，对连铸中间包熔池流场进行了三维数值模拟．预测结果表明，在中间包内设置流动控制装置可以更好地控制其中的流动情况．流场预测与实测的流谱定性上基本一致，表明φ－Ω法在三维复杂湍流流场模拟方面是可行的 Using the vector flow function-vorticity (φ-Ω) method, a three-dimensional numerical simulation of the flow field in the molten pool of a continuous casting tundish was carried out by using K-ε two-equation turbulence model. The results show that the flow control device in the tundish can better control the flow in the tundish. The prediction of flow field is qualitatively consistent with the measured flow spectrum, which shows that φ-Ω method is feasible in 3D turbulent flow field simulation
