Abstract
The effect of global warming is inducing sea ice retreat and transforming the Arctic into a navigable ocean. The melted ice cover can result in an environment where pancake-shaped ice floes are floating on sea surface; however, the effect of such an ice condition on ship performance has yet to be understood. This work develops a numerical model to predict the ship resistance in this typical case. Building on a traditional computational model for predicting ship hydrodynamics in open ocean, the Discrete Element Method is incorporated to include ice floes, so as to achieve ship-wave-ice coupling; thus, the simulation innovatively considers the influence of fluid flow on the interaction process. Following validation against experiments, the proposed model has been shown capable of accurately predicting ship resistance in pancake ice condition. Subsequently, the relationship of the resistance with ship speed, ice concentration and floe size is investigated.
