A Numerical Study of Mixing Behavior in the Bath of a Converter

摘要：

　　A mathematical model of a converter was developed in this study.A number of parameters were studied and their effects on the mixing time were recorded in a top blown as well as in a combined top and bottom blown converter model.The numerical and experimental results showed a good relative difference of 2.5%and 6.1%for the cavity depth and radius,respectively.For the top blown converter,the predicted mixing time showed a good relative difference of 2.8%in comparison to the experimental data.In the combined top and bottom blown converter model,a coupled DPM and VOF model was used to describe the top blowing and the bottom blowing in the bath.In addition,a new volumetric method for calculating the mixing time was applied.The results showed that,on average,a 23.1%longer mixing time resulted from the volumetric method compared to the standard method,where discrete monitor pointswere used to track the mixing time.
