Abstract
The dynamic motion of liquid sloshing in a container due to an external excitation can cause pressure pulses that severely damage the structure. In this study, a 2D rectangular tank was used to numerically model the hydrodynamic characteristics of sloshing and the pressure response in a typical industrial container. Harmonic and ground motion excitations were considered, and seven recorded ground motions were used to simulate the pressures at specified monitoring points. The contributions of the filling depth, ground motion components, and damping baffle to the pressure response history under impulsive and convective mode were examined. Based on the analysis of the dynamic response, a suitable damping baffle system was developed for all seismic excitations. The results of this work contribute toward improving tank design in earthquake-prone regions of the world.
