以钢包模型为例探讨科氏力对钢包浇注过程数学模拟的影响

摘要：流体会受到由于地球自转而产生的科氏力作用，而冶金领域绝大多数的流体数模中并未考虑科氏力。科氏力是一种特殊的影响因素，对模拟结果的影响究竟有多大，是非常值得探讨的问题。基于一种简单的、已验证过的钢包模型对科氏力的作用效果进行研究。通过对加载不同科氏力的模拟结果进行量化分析，解析科氏力在整个浇注过程中的作用。研究结果显示科氏力的作用效果受到物理量性质、环境混乱度、纬度、空间条件的影响。因此，在模拟计算中应基于实际情况考虑科氏力的作用。

Influence of Coriolis force on mathematical simulation results of ladle teeming of a ladle model

Fluid is affected by the Coriolis force due to the rotation of the earth, which is often ignored in fluid mathematical simulations in metallurgy. The Coriolis force is a unique factor, and it is worth investigating how much influence it has on the simulation results. Based on a simple and verified ladle model, the role of the Coriolis force in the whole teeming process was quantitatively analyzed by applying different Coriolis forces to the model. The results show that the effects of the Coriolis force are influenced by the nature of physical properties, environmental chaos, latitude, and space condition. Therefore, in a simulation, the influence of the Coriolis force should be considered based on the actual situation.
