Title: Sloshing Analysis in Prismatic Tanks Based on VOF Method

Abstract:
In order to simulate the sloshing in the prismatic tanks, a partial  cell parameter is
introduced to improve the original VOF method in uniform grid. An emphasis is given to
the numerical treatment of the free surface boundary velocity, which eliminates the
instability of the improved VOF method in some boundary cells. Then the improved VOF 
method was used to simulate the sloshing on the prismatic tank model  with different
filling levels and exciting periods. The numerical results of free surface elevation
history and pressure histories at different points of the tank model are compared with
experiment data.  Some engineering application examples are also presented for further 
validation.
