摘要
应用湍流流动的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停留时间作了模拟与分析 ,并预报了在不同位置加设不同高度的堰坝后中间包内钢液的流动状态及停留时间 结果表明 :如果二重堰的设置不当 。
The model about turbulent was applied to study fluid flow and its mixing in continuous casting tundishes.This 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 a computer,and the structure of the tundish has been improved.In this paper,the author only discussed that the weir dams with different heights were located at the different positions in the tundish.The results are:the properly improved flow fields do better than the old ones and the random location of the weir dam in the tundish may cause a worse flow field.
