“…These techniques require mesh motion algorithms and remeshing techniques to adapt the discretization of the fluid surrounding the solid. Arbitrary Lagrangian–Eulerian (ALE) techniques (Sarrate et al , 2001; Hu et al , 2001; Baiges et al , 2017; Cai et al , 2021) have been extensively used to include mesh motions in the governing equations. Sliding meshes have also been proposed for tracking rigid solids (Devolder et al , 2018).…”

Purpose This paper aims to report the study of a fluid buoy system that includes wave effects, with particular emphasis on validating the numerical results with experimental data. Design/methodology/approach A fluid–solid coupled algorithm is proposed to describe the motion of a rigid buoy under the effects of waves. The Navier–Stokes equations are solved with the open-source finite volume package Code Saturne, in which a free-surface capture technique and equations of motion for the solid are implemented. An ad hoc experiment on a laboratory scale is built. A buoy is placed into a tank partially filled with water; the tank is mounted into a shake table and subjected to controlled motion that promotes waves. The experiment allows for recording the evolution of the free surface at the control points using the ultrasonic sensors and the movement of the buoy by tracking the markers by postprocessing the recorded videos. The numerical results are validated by comparison with the experimental data. Findings The implemented free-surface technique, developed within the framework of the finite-volume method, is validated. The best-obtained agreement is for small amplitudes compatible with the waves evolving under deep-water conditions. Second, the algorithm proposed to describe rigid-body motion, including wave analysis, is validated. The numerical body motion and wave pattern satisfactorily matched the experimental data. The complete 3D proposed model can realistically describe buoy motions under the effects of stationary waves. Originality/value The novel aspects of this study encompass the implementation of a fluid–structure interaction strategy to describe rigid-body motion, including wave effects in a finite-volume context, and the reported free-surface and buoy position measurements from experiments. To the best of the authors’ knowledge, the numerical strategy, the validation of the computed results and the experimental data are all original contributions of this work.

“…Sun et al [26] examined the impact of fluid viscosity on sloshing behavior using the SPH approach, demonstrating the relationship between viscosity and sloshing amplitude. Cai et al [27] evaluated the accuracy of different simulation approaches (VOF, SPH, ALE ) in predicting rigid body forces due to fluid movement in partially filled tanks, favoring SPH for this purpose. Ren and Vafaei [28] studied the seismic response of rectangular concrete tanks using both finite element numerical methods and the British Standards Institution [29] method, highlighting the suitability of the latter for certain earthquake scenarios while noting its limitations for high-frequency earthquakes.…”

This study aims to investigate sloshing height in liquid storage tanks using a coupled FE-SPH technique. A novel approach employing the Box-Behnken method for efficient analysis design is introduced, ensuring the consideration of key parameters to obtain accurate results. The Smoothed Particle Hydrodynamics (SPH) formulation is utilized to simulate liquid behavior under large amplitude sloshing waves, while the finite element method models the structural response. The analysis reveals that fluid height is the primary geometric parameter affecting sloshing, with tank length considered a secondary factor. The frequency characteristics of ground motion significantly influence sloshing height, thereby impacting the liquid's behavior in the container. For future studies, we recommend focusing on the Box-Behnken design parameters: Acceleration Spectrum Intensity ASI and liquid tank height. This research provides valuable insights into optimizing the design and analysis of liquid storage tanks, paving the way for enhanced structural safety and performance.

“…Craig et al [47] also showed that RANS simulation using k-ω was less accurate than its no-model flow counterpart. Recently, Cai et al [48] compared between different free surface capturing approaches (VoF, SPH, ALE) and they also compared the prediction accuracy of unsteady k-, LES-WALE and DES, and no-model. They found that the no-model and the LES model provided the best correlation to the experimental results, which is in line with our general findings but is not a complete answer as we know that the no-model approach is sub-optimal for complex sloshing flows while a full LES simulation is often excessively computationally intensive, especially in an industrial context.…”

On the Efficacy of Turbulence Modelling for Sloshing

et al. 2022

As part of a wider project to understand the applicability of utilising slosh-based damping for wing-like structures, simulations of partially filled tanks subjected to harmonically oscillating and vertical motion are presented. The Volume of Fluid modelling approach is used to capture the air–water interface and different turbulence models based on the Reynolds Averaged Navier–Stokes equations employed. No-model simulations are also conducted to demonstrate the efficacy of using turbulence models in the simulation of sloshing flows. Accuracy of the models is assessed by comparing with recent well-validated experimental data in terms of the damping effect of the sloshing. A wide range of excitation amplitudes are considered in the study to demonstrate the effectiveness of different turbulence models in representing the flow feature of weak and very violent sloshing. The results show that standard turbulence models can produce an excessive dissipation, especially at the interface, leading to inaccuracies in the estimation of sloshing dynamics of the violent sloshing. This issue is absent in the no-model simulations, and better results are obtained for all tested sloshing conditions, suggesting approaches to mitigate this interfacial dissipation within RANS-based modelling is an important consideration for future direction.
