Abstract
The fractionation and mold filling of semisolid slurries were numerically i nvestigated for a range of mold geometry, inflow velocity, nozzle diameter, and fraction solid, The slurry was assumed to be a shear-thinning, non-New tonian fluid. Fractionation was determined from the trajectories of isother mal particles injected into the slurry. The results indicate fractionation is reduced with a tapered mold, high-inflow velocity, large nozzle diameter relative to mold, and low fraction solid.
