研究出一个表示连铸机中间包内的湍流流动和混合的数学模型,该模型包括求解三维湍流Navier-Stokes方程和K-ε两方程的湍流模型.对矩形断面中间包的流动参数和停留时间作出了预报,然后又用这一模型预报一般工业用的中间包流场,这种中间包的侧墙是稍有倾斜,而不是垂直的.结果表明,流场起了变化,这一点也可能对工业上的应用产生重大影响.把理论上的预报结果与水模型中的测量值作了比较.对中间包内的流场的认识也是设计最优化的依据.
A mathematical model for turbulent flow and mixing in a caster tundish has been developed, which includes a turbulence model for solving three-dimensional turbulent Navier-Stokes equations and K-ε two equations.The flow parameters and residence time The model was then used to predict the general industrial tundish flow field, which had a slightly tilted side wall instead of a vertical one and the result showed that the flow field had changed, which may also be Has a significant impact on industrial applications, and compares the theoretical predictions with measured values in the water model. The knowledge of the flow field within the tundish is also the basis for design optimization.
