Abstract
Ice-water coupling is a unique fluid-solid interaction problem characterized by collisions and hydrodynamic interaction between multiple bodies, accompanied by significant changes in the free surface. This paper presents a novel numerical model that achieves two-way coupling between the moving particle semi-implicit (MPS) method and the non-smooth discrete element method (NDEM) to simulate ice-water interactions. The MPS method is employed to model fluid motion, while the NDEM is applied to simulate the motion and collision of ice floes. The improved MPS method presented in this study, based on our previous research, addresses several issues found in the traditional MPS method. To improve the computational efficiency, the domain decomposition method is implemented to parallel the fluid solver and the AMG preconditioned GMRES iterative solver is selected as the optimal solution scheme for the improved MPS method. The accuracy and feasibility of the present coupling model are validated through benchmark cases, such as dam break, wave motion, ice motion in regular waves and debris dam break flow. Furthermore, the simulation of the ship moving in the broken ice field is successfully conducted with the coupling model and the influence of ice-water coupling load on predicting broken ice resistance is also investigated.
