A CFD application for modelling submerged gas injection in a Peirce-Smith converter.

A commercial computational fluid dynamics code was used to solve isothermal flow fields of gas and liquid in a Peirce-Smith converter. The model was validated with a quarter-scale water model and parametric study. Limits of the modelling technique used were recognised, but calculated results indicate that the model predicts the general flow field with reasonable accuracy. The model was used to examine general flow conditions in an industrial scale Peirce-Smith converter. Typical scaling factors of physical models were also evaluated with the aid of predicted bubble distribution, patterns of the flow fields and magnitude of flow velocities.
