“…As for the simulation of this kind of fluid motion, particle methods based on the Lagrangian description have an essential advantage. The famous particle methods, such as the famous Smoothed Particle Hydrodynamics (SPH) method [16] and Moving Particle Semi-implicit (MPS) method [17], have been widely applied in the simulation of liquid sloshing [18][19][20][21]. For example, Delorme et al [22] studied the pressure fields in the case of shallow water sloshing by SPH method.…”

Understanding the damping mechanism of baffles is helpful to make more reasonable use of them in suppressing liquid sloshing. In this study, the damping effect and mechanism of vertical baffles in shallow liquid sloshing under a rotational excitation are investigated by an improved particle method. By incorporation of a background mesh scheme and a modified pressure gradient model, the accuracy of impact pressure during sloshing is significantly enhanced. Combined with the advantages of the particle method, the present numerical method is a wonderful tool for the investigation of liquid sloshing issues. Through the analysis of impact pressure, the influences of baffle height and baffle position on the damping mechanism are discussed. The results show that the damping effect of vertical baffles increases with the increase of the elevation of baffle top and decreases with the increase of the elevation of the baffle bottom. Moreover, the resonance characteristics of sloshing are altered when static water is divided into two parts by the vertical baffle. The dominant damping mechanism of vertical baffles depends on the configurations.

“…In a subsequent paper, greater attention is given to energy considerations in the SPH-FE coupling, with interfacial energy compared and different structural models considered [101]. This work has since been extended to a full 3D SPH-FE coupling applied to complex applications, including tyre hydroplaning on rough ground, with good agreement shown against available analytical and experimental solutions [101]. Other recent popular couplings have involved using physics engines (such as Project Chrono) for moving structures with multiple members and SPH for the fluid [102].…”

Review of smoothed particle hydrodynamics: towards converged Lagrangian flow modelling

This paper presents a review of the progress of smoothed particle hydrodynamics (SPH) towards high-order converged simulations. As a mesh-free Lagrangian method suitable for complex flows with interfaces and multiple phases, SPH has developed considerably in the past decade. While original applications were in astrophysics, early engineering applications showed the versatility and robustness of the method without emphasis on accuracy and convergence. The early method was of weakly compressible form resulting in noisy pressures due to spurious pressure waves. This was effectively removed in the incompressible (divergence-free) form which followed; since then the weakly compressible form has been advanced, reducing pressure noise. Now numerical convergence studies are standard. While the method is computationally demanding on conventional processors, it is well suited to parallel processing on massively parallel computing and graphics processing units. Applications are diverse and encompass wave–structure interaction, geophysical flows due to landslides, nuclear sludge flows, welding, gearbox flows and many others. In the state of the art, convergence is typically between the first- and second-order theoretical limits. Recent advances are improving convergence to fourth order (and higher) and these will also be outlined. This can be necessary to resolve multi-scale aspects of turbulent flow.

“…Several approaches can be applied to discretize the equation based on how the geometry boundary is characterized, i.e. by particles or discrete segments [45]. In this paper, since we already use feature-surface, feature-curve and singularity particles to discretize the geometry boundaries, the fully discretized form of the gradient operator is employed,…”

In this paper, we present a feature-aware SPH method for the concurrent and automated isotropic unstructured mesh generation. Two additional objectives are achieved with the proposed method compared to the original SPH-based mesh generator . First, a feature boundary correction term is introduced to address the issue of incomplete kernel support at the boundary vicinity. The mesh generation of feature curves, feature surfaces and volumes can be handled concurrently without explicitly following a dimensional sequence. Second, a two-phase model is proposed to characterize the mesh-generation procedure by a feature-size-adaptation phase and a mesh-quality-optimization phase. By proposing a new error measurement criterion and an adaptive control system with two sets of simulation parameters, the objectives of faster feature-size adaptation and local mesh-quality improvement are merged into a consistent framework. The proposed method
