In this study, 3D flow fields, sump profiles and macrosegregation patterns are predicted for HDC slabs of an Al–4.5 wt.% Cu alloy. Numerical simulations are used to provide initial estimates of these features and the influence of slab geometry for a constant inlet configuration. In general, the heat conduction across the slab thickness controls the sump depth and general macrosegregation profile in the slab. As a result, the slab width does not significantly influence the qualitative sump shape or macrosegregation features and a 2D model is sufficient for establishing processing trends in HDC.
