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.
