Validation of Three-phase CAS-OB CFD-Model∗

In this paper CAS-OB ladle process has been studied with three-phase CFD model. Model was validated against the literature, where similar system was studied with physical model and industrial setup. The simulations were performed with the OpenFOAM®-2.3.0 CfD software package. Multifluid CFD model was used instead of traditional Volume of Fluid (VOF) formulation to capture the produced bubble plume and the slag-steel interface features with the same model. Turbulence was take into account with Large Eddy Scale (LES) turbulence model. As a result, the used computational mesh together with argon injection the produced bubble plume is presented. The obtained plume velocity profile and the slag-free open-eye area are also presented and compared against the experimental data from the literature, which were found to be in good agreement. In the future the presented model could be used to study the details of the CAS-OB process, like wearing of the refractory lining.
