Developing New Numerical Modeling for Sloshing Behavior in Two-Dimensional Tanks Based on Nonlinear Finite-Element Method

In this paper, the nonlinear sloshing behavior of a liquid in a partially filled tank is studied using the finite-element method (FEM) based on new spherical Hankel shape functions. The liquid free surface is one of the important parameters in the modeling of the sloshing problems. The main aim of this study is the determination of the free surface location using a new finite-element technique. In this new method, the finite-element method with...
