摘要：

Natural convection has received less attention than conduction in metal solidification processes. It may play an important role in solidification due to its potential influence on solutes distribution in melts and grain structure. A coupled mathematical model has been developed to simulate the solidification phenomena of squeeze cast magnesium alloy (AM50). An analysis based on a Control-Volume Finite Difference approach and an Enthalpy Transforming Model was carried out to understand the heat transfer and fluid flow in a cylindrical casting during solidification. The effect of natural convection on the total solidification process of squeeze casting AM50 was examined under various processing parameters, and comparison results are presented and analyzed.
