Sloshing behaviours of rectangular and cylindrical liquid tanks subjected to harmonic and seismic excitations

Abstract

A numerical and experimental study on the sloshing behaviours of cylindrical and rectangular liquid tanks is addressed. A three-dimensional boundary element method for space with the second-order Taylor series expansion in time is established to simulate the sloshing phenomenon and its related physical quantities inside a liquid tank subjected to horizontal harmonic oscillations or recorded earthquake excitations. The small-scale model experiments are carried out to verify some results of numerical methods in this study. The comparisons between numerical and experimental results show that the numerical method is reliable for both kinds of ground excitations. Finally, the water wave and the base shear force of a rectangular tank due to harmonic excitation are also presented at different frequencies. A huge cylindrical water tank subjected to a recorded earthquake excitation is used for application and discussion.

A 3D BEM model for liquid sloshing in baffled tanks

“…Assuming a laminar boundary layer, Jamali [17] introduced a solution to the liquid surface motion via a combinatory use of BEM and the finite difference method and then calculated the damping rate. Chen et al [18] employed a 3D BEM to study the sloshing behavior of cylindrical and cubic liquid tanks under harmonic and seismic excitations.…”

CFD Analysis of Non-Linear Sloshing in a Cylindrical Tank

“…Numerical results in terms of sloshing or wave height measured at right end of the computational domain are compared with experimental results given by Yung -Hsiang Chen et.al. [1]. Sloshing or wave height is measured using volume integral method.…”

“…On the other hand, mining tremors, which are induced due to mining activity of human being, are usually considered to be less severe due to lower acceleration levels observed. A relatively large number of numerical analyses has been focused on the behaviour of different types of steel tanks under earthquakes (see, for example, [3,4]), although, the results of the experimental studies are quite limited. On the other hand, few studies have been conducted so far concerning the behaviour of steel tanks under mining tremors (see [2]).…”
