Abstract

Large-eddy simulations (LES) of a continuous tundish with turbo-stoppers flows are presented. The numerical computations are performed by solving the conservation equations for compressible fluids. An implicit dual time stepping scheme combined with low Mach number preconditioning and a multigrid accelerating technique is developed for LES computations. The method is validated by comparing data of turbulent pipe flow at Reτ=1280 at different Mach numbers with experimental findings from the literature. Finally, the characteristics of the turbulent flow in a one-strand tundish with turbo-stoppers is analyzed and discussed. The comparison of LES findings of the implicit method with experimental data from literature showed very good agreement for the mean velocity profiles and the turbulence intensity distributions in the tundish.
