Abstract
The purpose of this study is to propose an effective technique for precise prediction of casting defect of injection molded part made from Mg alloy. In this study, the numerical simulation code based on FAVOR method was employed to investigate the flow of molten Mg alloy. At first, the simple fin flow was simulated to discuss the effect of calculated lattice on its flow behavior. The two types of fin model in which the longitudinal angle between the coordinate was different were prepared and its filling behavior was calculated by using simulation code based on FAVOR method and conventional method of SOLA-VOF. Calculated results revealed that significant difference of flow behavior was confirmed when the conventional method was used, while calculated results of FAVOR method shows almost same flow behavior even if the longitudinal angle was changed. The demonstration of FAVOR method was also performed by using complex actual casting model. The demonstrated results showed that the effect of calculated lattice on flow behavior was decreased by using FAVOR method.
