Abstract

Abstract: This study presents a novel three-phase Fluid–Structure Interaction (FSI) model for simulating the containment of oil spills. The model uses Level Sets to capture the evolution of multiple interfaces and incorporates spring forces on the structure under hybrid wave–current boundary conditions. The implementation of spring forces has been validated through simple harmonic motion models and a wedge falling simulation demonstrates the model's ability to handle multi-phase deformation. The study compares numerical results with experimental data to study the response of oil spills to wave–current hybrid conditions. Our simulations reveal that when the current exceeds 0.2 m/s, the movement of the boom is dominated by the current and not by the waves or their inertia, providing important information for the design of effective oil spill containment systems. Highlights: A novel three-phase numerical model for simulating oil spill containment using Level Sets to capture multiple interfaces. The implementation of spring forces in the Fluid–Structure Interaction algorithm within one-fluid formulation. Hybrid wave–current boundary conditions are introduced. Study of the response of rigid floating oil booms to wave–current hybrid conditions.
