| Abstract: |
| The numerical simulation of three-dimensional large amplitude liquid sloshing in cylindrical container is discussed in this paper. The ALE (Arbitrary Lagrange-Euler) kinematic description is introduced into the finite element fractional step method. The corresponding discrete numerical equations are developed by Galerkin weighted residual method afterwards. The boundary condition about free-surface tension is represented in the form of weak integration. The formulations to calculate the normal vectors of the mesh points on the three dimensional free surface is presented. Three-dimensional large amplitude liquid sloshing in a cylindrical tank is simulated and some important nonlinear characteristics of three-dimensional nonlinear liquid sloshing are obtained. The numerical results are compared with experimental results and the effectiveness of the method conducted in this paper is demonstrated. |
