Abstract

Some of the effects of capillary forces and the solid-liquid contact angle have been incorporated into previously known solutions for solidification shrinkage void profiles. Comparisons are then drawn between the original profiles from the literature and the modified capillary result. Since the capillary rise is a function of the gravitational acceleration, the new solution could also be extended down to reduced gravity conditions. We feel these results will lead to a better understanding of solidification shrinkage void shapes in a variety of circumstances.
