OPENFOAM SIMULATIONS OF ISOTHERMAL PHASE-CHANGE IN THE ABSENCE AND PRESENCE OF SHRINKAGE

摘要：

Introduction Solidification and melting of metals are phase-change phenomena,which take place at a single temperature for pure metals,or at a range of temperatures for metal alloys.In this work,we focused only on phase-change of pure metals,i.e.isothermal phase change.Most metals have higher density in the solid phase than in the liquid phase.Therefore,during their solidification,their overall volume shrinks.This phenomenon is refereed to macro-shrinkage.
