Experimental and numerical simulation of casting process in a ladle

With the commercial software pack of CFD,the experimental and by using VOF model and standard k-e turbulent model in a 60 t ladle casting process were carried out.The forming and developing regulation of the vortex in the casting process was analyzed by the relationship between mass flow rate at nozzle and liquid height.A velocity field of the free liquid surface was obtained when the vortex was formed.Compared with the experimental results,it shows that the numerical results about the effect of nozzle's diameter and nozzle's position on the vortex agree with the experimental results well.The results also indicate that the VOF models are available for the simulation of flows in this process.
