Abstract

Elucidation of sloshing phenomenon is very important to reduce the damage of the tank in an engineering field. In this paper, a simulation of the tank sloshing using three-dimensional particle method is introduced. The accuracy validation of the sloshing of a rectangular tank is done through comparison with the results from the experiment and finite element method. In the simulation of a cylindrical tank, the water surface deformed corresponding to the natural period. In addition, swirl phenomenon was confirmed under the condition of vibrating the tank for a long time. These results show that the MPS method can apply to the three dimensional tank sloshing.
