Abstract:
In this study, the fluid flow behaviour of a copper slag-matte in an industrial Peirce- Smith converter was simulated numerically in 2-D and 3-D by use of volume of fluid and realisable k-ε turbulence model. These models could satisfactorily account for the multiphase and turbulent flow and were implemented using commercial computational fluid dynamics numerical code, viz. FLUENT. Moreover, a cold model was constructed for physical simulations by use of a Perspex container with seven tuyeres on one side of the cylinder representative of the Peirce Smith converter. Compressed air was blown into the cylinder through the tuyeres to simulate oxygen enriched air injection into the vessel. Industrial feed, product and by-product referred to as matte-white metal and slag were simulated with water and kerosene respectively. The influence of blowing conditions on the distribution of phases was studied with compressed air flow at constant simulated matte and slag ratios. Both numerical and experimental simulations were able to predict the dispersion characteristics of the system in relation to flow and have led to significant insights into the fluid dynamics of Peirce-Smith converters.
