Investigation of gas purging configuration in an industrial ladle by computational fluid dynamics

A three-dimensional model was developed to investigate the effects of gas nozzle configuration in an industrial gas-stirred ladle on flow pattern, mixing time, heat transfer, inclusion removal, and shear stress wall. Population balance coupled with computational fluid dynamics chosen evaluate removal. The properties phases size distribution were agreement literature data. Gas locations investigated terms radius angle. It found that increase angle decrease location decreased Also, as got closer each other, bubble plumes overlapped, turbulent kinetics affected. This turn affected temperature, Therefore, by changing radius, these parameters did not have similar trends. From performed investigations, it best injection 140° 0.65R. Shear stress, time removal at plug 0.65R improved 38.7%, 1.3%, 0.87%, respectively. In addition, 140°, increased 6%, −6.57%, 8%, By choosing this location, performance optimum all parameters.
