Numerical study on the movement pattern of ice around the ship in the broken ice field
Paper i proceeding, 2023

Broken ice field is among the common type of ice conditions when ships operate in Arctic navigation, where ships face a significant increase in resistance and local structural safety threats due to the interaction between the ship's hull, water, and broken ice. The hull needs to remove a large amount of broken ice from its path and disturb the surrounding broken ice, and the extent to which can reflect the intensity of the ship-water-ice interaction. In this study, a coupled CFD-DEM approach to simulate ship-water-ice interaction-related phenomena. In the calculation process, rigid particles are considered as non-rebreakable broken ice, while the effect of ship wave variations on the movement of broken ice is taken into account. The "ice boundary layer" (IBL) is found in the numerical results, and distribution of the thickness of "IBL" along the ship's bow is derived and in good agreement with the formula proposed by Aboulazm (1989). After that, the relationship between ship speed on the movement of ice is also studied.
