Ice-going ships play a crucial role in polar transportation and resource extraction. Different from the existing modeling approach which assumes that ships remain stationary, dynamic overset grid technology and DFBI (Dynamic Fluid-Body Interaction) method are employed in this paper to enable the free-running motion of the ship in modeling. A numerical model capable of simulating a ship navigating through pack ice area is proposed, which uses Computational Fluid Dynamics (CFD) method to solve the flow field and applies the Discrete Element Method (DEM) to simulate ship-ice and ice-ice interactions. Besides, the proposed high-precision method for generating pack ice area can be used in conjunction with the proposed numerical model. By comparing the numerical results with the available model test data and experimental observations, the effectiveness of the numerical model is validated, demonstrating its strong capability of predicting resistance and simulating ship navigation in pack ice, as well as its significant potential and applicability for further studies.
