CFD Investigation of Rotational Sloshing Waves in a Top-Submerged-Lance Metal Bath

Abstract Computational fluid dynamics (CFD) is applied to investigate rotational sloshing waves in a top-submerged-lance (TSL) cylindrical metal bath. The study an extension of recent work the authors, where top injection Ar into metallic bath was examined quasi-2D flat setup, allowing numerical model be extensively validated against experimental data based on x-ray radiography. new analysis gas vessel reveals appearance bath, which maintained by condition synchronism between bubbles and free surface A quantification achieved with specific post-processing simulation results, showing effect control parameters such as lance immersion depth flow rate. This fundamental research demonstrates capability CFD modeling predict known from literature practice, understanding essential for design TSL furnaces.
