The two-dimensional Volume of Fluid method (VOF) is extended for the study of liquid sloshing in cylindrical containers subjected to lateral excitation. A number of improvements have been made to the original VOF method. These include taking into account the free surface orientation, transporting hexahedral shaped fluid from cell to cell and considering velocity condition on curved boundaries in partial cell treatment. The results of newly improved algorithm agree well with experimental data. The swirl response of free surface in a cylindrical container due to dynamic instibility are observed in numerical examples.
