“…The SPH implementation in DualSPHysics [17] provides several tools and features that make the code ready for engineering applications, and very efficient when fluid phases are relevant [more in 18]. During the last few years, the code has seen an increase in availability of functionalities that are very apt for the simulation of Fluid-Structure Interaction in different engineering fields, ranging from renewable energy device [19,20,21] to hydroelasticity problems [22,23,24,25]. The code, moreover, proved its reliability for nearly any kind of free-surface flow interacting with rigid structures: dambreak-induced violent flows on downhill structures [26,27], coastal breakwaters [28,29] or floating objects [30,31,32].…”

Sloshing phenomena regard the dynamic excitation of a partially filled tank which leads to the motion of the fluid within. The dynamic effects, especially if the excitation frequency approaches the natural frequency of the tank (near resonance), may compromise the structure stability. Amplification of motion may be either pursued or avoided, depending on the design purposes; regardless, it is important to predict the coupled effects generated by the tank interacting with the contained liquid. The present study aims to offer a simplified approach along with valid parameters that link the filling level of the tank to the sloshing mode of vibration. The parameterization procedure is numerically supported by a Computational Fluid Dynamics (CFD) solver based upon the Smoothed Particles Hydrodynamics (SPH) meshless method. Within the proposed framework, a parametric sloshing tank is simulated and validated using experimental data as a test-rig, therefore used to perform a wide sensitivity study by changing the filling ratio. The numerical results interpretation leads to a method which can synthetically predict the characterizing frequency of the phenomenon using a semi-analytical fitting, with improved accuracy over previous literature methods. This procedure is established within the open-source SPH-based DualSPHysics, and provides a reliable alternative to traditional approaches, proving that validated numerical methods can directly support the design of sloshing tanks, with all the advantages related: quickness, affordability and reproducibility. 4402COMPDYN 2023 9 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.

“…DualSPHysics [25] is an advanced meshless solver with emphasis on free-surface flow modeling and has been shown to be robust and accurate in a wide range of applications: reproducing extreme wave events [26], coastal engineering simulations [27,28], fluid-solid interaction (FSI) [29,30], wave energy converters [31][32][33][34][35], etc. The peculiarities of this solver make it suitable for dam-break simulations, since it is naturally able to handle large deformations and violent impacts that involve solid obstacles [36,37]; it follows that SPH-based numerical models could be as effective as, if not better than, the traditional methods applied to the dam failure records, such as the ones based on 2D SWEs [38,39] or the VOF-or FEM-based [40,41] models.…”

The presence downstream of a dam of either rigid or erodible obstacles may strongly affect the flood wave propagation, and this complex interaction may lead to further dramatic consequences on people and structures. The open-source Lagrangian-based DualSPHysics solver was used to simulate a three-dimensional dam-break in a closed domain including an oriented obstacle that deflects the flow, thus increasing the complexity of fluid dynamics. By comparing numerical results with experimental data, the effectiveness of the model was evaluated and demonstrated with an extensive sensitivity analysis based on several parameters crucial to the smoothed particle hydrodynamics method, such as the resolution, the boundary conditions, and the properties of the interaction weight function. Charts and summary tables highlight the most suitable conditions for simulating such occurrences in the DualSPHysics framework. The presence of the obstacle, being also an opportunity for observation and study of complex fluid dynamics, opens the way to investigate the fluid interaction with solid objects involved in dam-break events and, possibly, to predict their effect with respect to the relative position between them and the flood and other relevant parameters. Finally, the numerical model presents a good overall agreement.
