Abstract. Liquid sloshing in tanks has many important applications in a variety of engineering fields. In this study, based on a CFD solver, a numerical model is developed to study the liquid water sloshing in two-and three-dimensional tanks. The VOF method is used to capture the fluid interface. In order to validate the proposed model, a 2-D liquid-water sloshing problem was first solved. The variations of the pressure at the monitor point 100 mm below the initial free surface were recorded. Then the method was applied to a 3-D liquid-water sloshing problem and the sloshing-induced moment was obtained. The numerical results were compared and analyzed with experimental measurements. The results confirm that the present method can be adopted to predict the motion of liquid water and analyze its induced moment on the tank boundary when it has a roll motion.

“…4 (b), the boundary pressures have been interpolated from the fluid particles directly and thus they are not linked to the kernel function of the boundary particles. To further demonstrate our improvement in the pressure predictions on the solid boundary, we also computed the sloshing case of Chen et al (2013) and compared with their experimental data and SPH computations using an advanced coupled dynamic solid boundary. The schematic setup of the sloshing tank is shown in Fig.…”

“…A constant time step of t  = 5 × 10 -5 s is used for the frog-leap time integration. Due to the accumulation of numerical dissipations as the time progresses, the experimental and numerical data were analyzed within the first 20 s of the simulation by following the recommendation of Chen et al (2013). This cost about 50 hours of CPU time on a DELL workstation (CPU Intel X5675 3.0 GHz).…”

A stabilized incompressible smoothed particle hydrodynamics (ISPH) method with the addition of a density invariant relaxation condition in the pressure calculations is applied to simulations of highly nonlinear liquid sloshing problems. By applying the Neumann boundary condition when solving pressure, the performance of the present ISPH method is enhanced significantly. Two large-amplitude free sloshing problems under a resonance sway excitation were carried out in a square and a rectangular tank with filling-depths ratios of 20% and 50% of tank height, respectively, and compared with the available published experimental results. To extend the validation of the method, numerical simulations for sloshing problems with the varying density of a floating body as well as a middle baffle, which also generates strongly nonlinear free surface flow, were conducted. The results showed that the present ISPH method produces smooth pressure distribution and significantly reduces spurious oscillation. The proposed ISPH method was shown to be robust and accurate in long time simulation of highly nonlinear sloshing problems.
