摘      要：A validated numerical model was established to simulate gas−liquid flow behaviors in the oxygen-enriched side-blown bath *** model included the slip velocity between phases and the gas thermal expansion *** modeling results were verified with theoretical correlations and experiments,and the nozzle-eroded states in practice were also involved in the *** comparison,it is confirmed that the thermal expansion effect influences the flow pattern significantly,which may lead to the backward motion of airflow and create a potential risk to production ***,the influences of air injection velocity and furnace width on airflow behavior were investigated to provide operating and design *** is found that the thin layer melt,which avoids high-rate oxygen airflow eroding nozzles,shrinks as the injection velocity increases,but safety can be guaranteed when the velocity ranges from 175 to 275 m/***,the isoline patterns and heights of thin layers change slightly when the furnace width increases from 2.2 to 2.8 m,indicating that the furnace width shows a limited influence on production safety.
