Monolithic 3D numerical modeling of granular cargo movement on bulk carriers in waves

A novel monolithic approach for simulating vessels in waves with granular cargo is presented using a Finite Volume framework. The integrated approach aims to develop a tool for maritime safety analysis and design optimization of bulk carriers. The computational model integrates a three-phase Volume of Fluid method to represent air, water, and cargo, coupled with a material model that applies a rigid-perfectly plastic material model for the granular phase. The approach takes into account the floating motion of the ship using a rigid body motion solver for three degrees of freedom and is supplemented by inviscid far-field boundary conditions facilitating the generation of linear waves approaching the vessel. The model's efficacy is demonstrated through a validation of the three-phase Volume of the Fluid method, a verification of the granular material model, and finally, a reconstruction of the accident of the “Jian Fu Star” bulk carrier in a fully 3D simulation.
