NUMERICAL SIMULATION OF LIQUID SURFACE VIBRATION IN A RECTANGULAR TANK USING A REFINED PARTICLE METHOD

Abstract

Numerical simulation of liquid surface vibration in a rectangular tank using a refined particle method is introduced in this study. The original MPS method has not solved the problem to decrease energy dissipation. The authors simulate the forced vibration and obtain a good result comparing the simulation result with the result of an experiment and a finite element method. In the simulation of free vibration, the water level agrees well to a nonlinear analytical solution. The study suggests that the precise method of the gradient operator is useful to reduce the energy dissipation of the original MPS.
