Unsteady fluid flows and level fluctuations in a thin slab continuous casting mould have significant influence on product quality.In this study,the phenomena concerning transient flow features and free surface motions were analyzed by means of the large eddy simulation (LES) software with the smagorinsky SGS model-VisualCast (VCast) II,where the Simpler algorithm on a body-fitted mesh was used to resolve governing equations.A series of water analog experiments on the fluid flow and the surface wave in the moulds of thin slab continuous casting were also performed.The results of fluid regions,middle of vortex and level fluctuation from digital simulations were identical with the results of the water analog experiments.
