Simulation of Nonlinear Sloshing Behaviors under Dynamic Actions

Abstract:

This paper simulated the non-linear sloshing effects under typical dynamic actions. The sloshing simulation is realized with the Arbitrary Lagrangian Euleria (ALE) formulation plus bi-phase hydrodynamic biomaterial liquid gas materials. The study first investigated two dimensional (2D) sloshing problems under harmonic excitations. Through calibration studies in standard rectangular tanks, the case study demonstrated reasonable agreement with numerical results published by other researchers. The study was then extended to more complicated three dimensional (3D) sloshing problems, with the fluid-structure interaction (FSI) considered. The simulation well reflected the sloshing behaviours in a steel tank subject to given seismic excitations and provided available prediction for structural performance. The obtained results show that the used method is helpful for seismic design of liquid tanks.
