Diploma Thesis, July 2004

ABSTRACT

The dynamic response of liquid storage vessels is characterized by sloshing, due to the motion of the liquid free surface. The present thesis aims at the numerical solution of this phenomenon in horizontal-cylindrical vessels of arbitrary depth. The solution is conducted through a source code of finite elements. Sloshing frequencies and modes are computed, as well as the hydrodynamic pressures and forces on the vessel wall, using a spectral method of analysis. The numerical results are compared with those from analytical solutions, where available.
