Abstract

A numerical model based on the SOLA-VOF method, which can calculate the transient free-surface configuration of the melt, has been developed in order to analyze melt flow in the investment mold. The computational results were compared with experimental results obtained from pure aluminum investment casting. Heat transfer analysis, with and without consideration of melt flow effect has been performed. It can be concluded that analysis of melt flow in the investment mold, provides the optimum conditions for gating design. It also enables more precise solidification simulation, since heat loss, while filling the thin and complex investment mold, plays an important role in determining the solidification sequence.
