Investigation to the numerical simulation approach for sloshing in tanks considering fluid-structure interaction

To study the effect of elastic structures in the containment system on sloshing impact pressures,a numerical approach with fluid-structure coupling technique based on explicit time integral FEM/FVM was developed for simulating motions of flow and fluid-structure interaction.The numerical approach with im-portant parameters was addressed first and was applied to 2D rigid rectangular tank case.The computational results were validated against CFD results and existing experimental data,showing good agreement.Then sloshing simulations in 3D rigid and elastic rectangular tank cases were carried out and the different effects on liquid motions in the tank and impact pressures on the walls were discussed.The results are meaningful to sloshing loads evaluation.
