Application of Arbitrary Lagrangian-Eulerian strips with fully nonlinear wave kinematics for force estimation

Csaba Pakozdi et al.

Summary: This article presents a novel approach to evaluate wave hydrodynamics of offshore structures without model test data by combining a nonlinear numerical wave tank with the Morison equation. The method provides accurate estimations of highly nonlinear and breaking waves at a reasonable computational cost, as validated by comparisons with analytical solutions and model test data.

Nonlinear liquid sloshing dynamics: Post-processing of conventional finite element solutions by digital filters

Nina L. Brietman et al.

Summary: The aim of this study is to develop a robust finite element procedure for solving 2D and 3D nonlinear liquid sloshing dynamics modelled by standard potential theory. The paper compares various techniques to enhance stability and mitigate numerical oscillations, and chooses the most robust stabilized finite element formulation. The proposed post-processing method allows for recovering more accurate nodal values from conventional finite element solutions.

The Effect of Porous Media on Wave-Induced Sloshing in a Floating Tank

Wen-Huai Tsao et al.

Summary: This study focuses on the application of porous media in mitigating sloshing and controlling vibration in LNG vessels and offshore structures. By placing porous media in a water tank, the dynamic characteristics of the sloshing fluid can be altered, leading to a damping effect that protects the integrity of a liquefied natural gas tank. The study investigates the interaction between the sloshing fluid and the floating body in an ocean environment, with a specific focus on wave-induced sloshing fluid and its interaction with the substructure. The results confirm the effectiveness of porous media in controlling vibration and mitigating sloshing response.

Lagrangian vs. Eulerian: An Analysis of Two Solution Methods for Free-Surface Flows and Fluid Solid Interaction Problems

Milad Rakhsha et al.

Summary: This study compared Eulerian and Lagrangian Computational Fluid Dynamics (CFD) approaches for solving free-surface and Fluid-Solid Interaction (FSI) problems, using different discretization techniques. The performance was evaluated through flow simulations around a cylinder, dam break tests, and two FSI problems involving floating rigid bodies and elastic gates interacting with the flow. Overall, the study discussed the robustness, ease of model setup, and versatility of the two approaches, both of which are open-source and available in the public domain.

Local simulation of sloshing jet in a rolling tank by viscous-inviscid interaction method

Wen-Huai Tsao et al.

Summary: This paper studies the local behavior of a jet induced by fluid impact using a new method called viscous-inviscid interaction (VII), which combines the inviscid Eulerian-Lagrangian scheme with additional sources to model viscous flow within the boundary layer. The volume of fluid (VOF) method is also used for comparison, showing good agreement with experimental results and maintaining efficiency.

Sloshing force in a rectangular tank with porous media

Wen-Huai Tsao et al.

Summary: The presence of porous media in a water tank has a significant impact on the dynamic characteristics of sloshing behavior, particularly during resonance when sloshing force is crucial. This paper presents an analytical equivalent mechanical model and numerical regularized boundary integral method (RBIM), which are validated through resonant tests. Experimental results show that the analytical solution is effective for linear-flow regimes, while the numerical method accurately predicts nonlinear-flow scenarios with the determination of suitable parameters.
