应用湍流流动数学模型研究了首钢中间包内钢液的流动与混合，该模型包括求解三维湍流的N-S方程和k-ε双方程模型.对首钢第二炼钢厂现有中间包的流场和钢液的停留时间做了模拟与分析，并预报了在不同位置加设不同高度的坝后，中间包内钢液的流动状态及停留时间.结果表明，如果坝的设置不当，中间包内钢液的流动状态则会更差.

The turbulent model was applied to study of the fluid flow and mixing in continuous casting tundishes.The mathematical model involves the solution of the three dimensional turbulent N-S equation and k-ε two equation turbulence model.The fluid flow field and residence time have been simulated and analyzed by computer,and the structure of the tundish has been improved.The author only discussed that the dams with different heights were located at the different positions in the tundish.The results show that the properly improved flow fields do better than the old ones and the random location of the dam in the tundish may cause the worse flow field.
