“…Further studies for the detailed analysis of air effects using a large number of particles are expected. In addition, for the engineering standpoints, it is expected to couple two-phase SPH with a mathematical model for ship motion to carry out fully coupled ship-tank simulations, which is similar to those discussed in References [57][58][59][60].…”

This study aimed to validate the single-phase and two-phase smoothed particle hydrodynamics (SPH) on sloshing in a tank. There have been many studies on sloshing in tanks based on meshless particle methods, but few researchers have used a large number of particles because there is a limitation on the total number of particles when using only CPUs. Additionally, few studies have investigated the influence of air phase on tank sloshing based on two-phase SPH. In this study, a dedicated sloshing experiment was conducted at the National Research Institute of Fishing Engineering using a prismatic tank with a four-degrees-of-freedom forced oscillation machine. Three pressure gauges were used to measure local pressure near the corners of the tank. The sloshing experiment was repeated for two different filling ratios, amplitudes, and frequencies of external oscillation. Next, a GPU-accelerated three-dimensional SPH simulation of sloshing was performed using the same conditions as the experiment with a large number of particles. Lastly, two-dimensional sloshing simulations based on single-phase and two-phase SPH were carried out to determine the importance of the air phase in terms of tank sloshing. Based on systematic comparisons of the single-phase SPH, two-phase SPH, and experimental results, this paper presents a detailed discussion of the role of air-phase in terms of sloshing. The currently achievable accuracy when using SPH is demonstrated together with a few sensitivity analyses of SPH parameters.

“…Sloshing in zero-gravity environment has been investigated for space vehicles with partially filled fuel tanks [1]. In marine vessels such as oil and gas tankers, the sloshing induced by ocean waves and its coupling with the ship motion have been extensively investigated [2][3][4]. In road/rail vehicles, the most well-known circumstance is the sloshing induced by the accelerating, braking, and turning manoeuvring of vehicles.…”

“…As a result, coupled vehicle-sloshing analysis often requires iterative interaction between two different solvers. For example, the coupled SPH-FEM analysis in [2], coupled BEM-CFD in [4], and BEM-FEM [10,15] studies in offshore engineering have been carried out. Although effective in solving violent coupled vehicle-sloshing problems, the computational effort is intensive.…”

This paper is concerned with liquid sloshing in a partially filled container due to 3-dimensional vehicle motion. The liquid sloshing is described by a set of linear modal equations derived from the potential flow theory, which can be applied to liquid sloshing induced by arbitrary combination of lateral, longitudinal, and rotational excitations. The sloshing force and moment are expressed with a set of hydrodynamic coefficients that are determined by the linear velocity potential. These coefficients can be precalculated and incorporated into the motion equations of the vehicle system so that a fully coupled vehicle-sloshing model is available. In addition, we propose an approach to calculate the hydrodynamic coefficients using the outputs of commercial frequency-domain boundary element software in order to maximize the efficiency of modelling and computation. The accuracy of the proposed model is examined by comparison with available CFD and model test data in the literature. The case of a road tanker encountering a road bump during acceleration/braking is investigated. Results show that the tank rotational motion will affect the amplitude and the sloshing force, and neglecting tank rotation may lead to underestimation of the sloshing force magnitude.

“…Experimental and numerical studies have been conducted to investigate the effect of the dimensions and the elasticity of the base of the tank and the frequency of the fluid-tank system on the sloshing under harmonic excitations [1][2][3][4][5][6][7][8][9][10]. Seakeeping problems by considering sloshing in tanks were investigated numerically with smoothed particle hydrodynamics (SPH)-finite element method (FEM) coupling [11]. A particle-based FSI solver was proposed to solve sloshing flows in roller tanks with elastic baffles [12].…”

Sloshing behavior due to near-fault type and earthquake excitations of a fluid in a tank having a highly deformable elastic structure in the middle was investigated experimentally and numerically in this paper. In the numerical model, fluid was simulated with smoothed particle hydrodynamics (SPH) and structure was simulated with the finite element method (FEM). The coupling was satisfied with contact mechanics. The δ-SPH scheme was adapted to lower the numerical oscillations. The proposed fluid-structure interaction (FSI) method can simulate the violent fluid-structure interaction problem successfully. The effects of near-fault type and earthquake excitations on free-surfaces of fluid and the elastic structure are presented.
