In this paper, sloshing phenomenon in a rectangular tank under a sway excitation is studied numerically and experimentally. Although considerable advances have occurred in the development of numerical and experimental techniques for studying liquid sloshing, discrepancies exist between these techniques, particularly in predicting time history of impact pressure. The aim of this paper is to study the sloshing phenomenon experimentally and numerically using the Smoothed Particle Hydrodynamics method. The algorithm is enhanced for accurately calculating impact load in sloshing flow. Experiments were conducted on a 1 : 30 scaled two-dimensional tank, undergoing translational motion along its longitudinal axis. Two different sloshing flows corresponding to the ratio of exciting frequency to natural frequency were studied. The numerical and experimental results are compared for both global and local parameters and show very good agreement.

“…The sloshing problem is relevant to the analysis of liquid transportation [1], the study of the effect of vibrations on liquid storage tanks [2,3] or liquid damper devices [4,5], and many other engineering applications. Several methods have been developed to study and predict free surface behaviour, such as experimental 5 studies, analytical solutions, and numerical methods [6,7,8,9,10].…”

“…During sloshing, an increase in velocity gradient can occur due to the wave-to-wall and wave-to-wave interactions. Many investigations [40,41] show that the wave-to-wave interaction is more effective. Also, it can be observed that the kinetic energy in cylindrical tank is slightly greater compared to the energy in rectangular tank, as can be expected according to sloshing levels.…”

Sloshing in medium size tanks caused by earthquake studied by SPH A numerical study of sloshing effects in medium-sized liquid storage tanks subjected to earthquake is briefly presented in the paper. The following issues are considered in the study: the phenomena occurring in tanks during excitation, the amount of pressure change during sloshing, and the effects on the tank itself. The numerical model used in the study is based on the Smoothed Particle Hydrodynamics (SPH) method. The presented method can be used for simulating main nonlinear characteristics of the fluid, such as viscosity, cavitation, wave breaking, and turbulence. The reliability of the model and some of its possibilities are illustrated on a practical example.
