Abstract: The Reynolds-averaged Navier Stokes (RANS) and large eddy simulation (LES) were utilized to predict the turbulent flow and the distribution of inclusions in tundish. The results showed that the flow field structure computed by RANS is symmetric, but the flow field calculated by LES is asymmetric. Moreover, the flow field can be described more accurate and comprehensive by LES. In addition, LES can capture more random vortexes from the flow field. Three inclusion trajectories are obtained, and the distribution of inclusions is also asymmetric. The wall and corner of the tundish are the place where inclusions gather easily.
