Sinopsis

The solidification of a binary-alloy in the presence of two-dimensional aligned fibers is investigated. The process simulates infiltration of fiber preforms as well as stir-casting of metal matrix composites. The energy equation is solved on a uniform computational grid for the temperature field using a modified enthalpy method which accounts for the fibrous phase. The species equation is solved for the solute distribution. The fibers are assumed to be non-reactive and only participate in the solidification process through heat conduction. The computational approach is highly efficient, and in spite of the complicated domain being modeled, solutions are obtained in under an hour on a workstation. The results obtained from the simulations in terms of the shape and movement of the interface compare well with those from a previously published study which uses a more cumbersome method.
