• Numerical investigation is made to study the effect of natural convection on the formation of macrosegregation of a Pb-Sn alloy solidification process in a 2-D confined rectangle mold. The governing equations are calculated using the continuum model theory with SIMPLE algorithm during the solidification process. In addition, to track the liquid-solid interface with time variations, the moving boundary condition is adopted and irregular interface shapes are treated with boundary-fitted coordinate system. As the temperature reduces from the liquidus to the solidus, the liquid concentration of Sn, the lighter constituent, increases. Then the buoyancy-driven flow due to temperature and liquid composition gradient, called thermosolutal convection or double diffusion, occurs in the mushy region and forms the complicated macrosegregation maps. Related to these phenomena, effects on the macrosegregation formation depending on the cooling condition and gravity value are also described.
