Numerical Study of Fluid Flow and Mixing in the Argon Oxygen Decarburization (AOD) Process

A three-dimensional (3D) model has been developed based on the Eulerian multiphase flow approach to investigate fluid behavior and mixing efficiency in multi-tuyere AOD process. The interphase forces, including drag force, lift virtual turbulent dispersion wall lubrication were incorporated into this model. was used simulate six-tuyere seven-tuyere processes. phenomena of multi-jet penetration, bubble plume merging, 3D characteristics considered. results indicate that merging occurs upper part liquid bath, forming a typical cluster. predicted penetration length for single tuyere jet agrees well with previous work. For system, side jets penetrate deeper than inside ones. good condition center while better pattern sidewall region lower bath. Overall, performs under same gas rate. These findings increase understanding process, allowing further optimization process parameters. This can be extended incorporate thermochemical reactions modeling reactor.
