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.
