AbstractThe goal of this study is to determine the influence of combo bag on the velocity and temperature fields in the liquid metal pool during the DC casting of aluminum ingots. For this, a 3D finite element solution algorithm is used to compute the flow and heat transfer phenomena. The solution approach is able to deal with high Reynolds number turbulent flows, buoyancy effects and flow through combo bag meshed openings. An isothermal study with turbulence modeling quantifies the effect of the combo bag on the flow and an effective viscosity is determined for the respective flow conditions. The coupled flow and heat transfer during ingot formation are solved for forced convection conditions (no buoyancy) and by including the natural convection terms. it is shown that the flow is driven by the inlet flow rate in the vicinity of the combo bag and by natural convection outside this region.
