Abstract

A large-eddy simulation using preconditioning is described and applied to investigate continuous tundish flow. The Navier-Stokes equations for compressible flow are approximately solved using an implicit dual-time stepping scheme combined with low Mach number preconditioning and a multigrid acceleration technique. The impact of a turbo-stopper on jet spreading, jet impingement on the wall, wall jets, and steel quality is investigated. The numerical analysis shows the turbostopper flow to generate a more homogeneous tundish flow and as such a higher steel quality can be expected.
