Influence of Geometric Parameters in Self-damping Efficiency of Rectangular Liquid Storage Tanks
Turbulent fluctuation of the liquid medium under lateral excitation is a major area of concern due to the potential severities it may cause if the contained structure is damaged. Therefore, this study focuses on variation in the self-damping efficiency of the liquid mass in a liquid tank under lateral excitation. For this, a parametric study has been carried out by changing the aspect ratio of the tank with respect to the horizontal and vertical dimensions. Pressure-based transient analysis has been carried out considering harmonic excitation as well as seismic ground motions. The transient response of the liquid medium is observed in terms of free surface elevation and hydrodynamic pressure. The study reveals that an accurate geometric design of the tank structure improves the self-damping of the sloshing liquid. An aspect ratio of less than ‘1’ results in the improved self-damping efficiency of the contained liquid mass. The effect of the vertical dimension of the tank on slosh damping is less significant compared with that of the horizontal dimension.
