Abstract
This study attempts to develop a better understanding of the solidification shrinkage process for cylindrical geometries. Experiments were carried out to observe the solidification sequence and void distribution for two different experimental liquids enclosed in Pyrex tubes. Tests were conducted both in the presence and absence of dissolved gases. A model was also developed that yields predictions of the correct order of magnitude and accounts for some of the trends observed experimentally. Finally, prospects for using soluble gases to control void distribution in applications such as phase-change-material heat pipes are discussed.
