 Abstract
In this paper, the well-known VOF method is implicitly modified to analyze the casting process. This modified method incorporated into SIMPLER algorithm is applied to the mold filling analysis in t wo-dimensional cavity casting process. The phase change analysis including the effect of residual flow after the completion of filling has also become performed. The results from the present method are compared with those of the explicit and implicit SOLA-VOF methods to examine the accuracy and efficiency of the present method. The results show that the present method is more efficient than the other two methods in the computational tune. It is also shown that the present method is superior to the SOLA-VOF method in the view of symmetry. The results also indicate that the mushy region is significantly influenced by the residual Bow at the initial slam of solidification.
