NUMERICAL SIMULATIONS OF ICE FLOES MOVEMENT AROUND AN OCEAN STRUCTURE USING A DISTRIBUTED MASS/DISCRETE FLOE MODEL

A recently proposed Distributed Mass/Discrete Flow (DMDF) model is a model for practical computations of floes motion. The floes are divided into bunches, in which they are assumed to be distributed uniformly. As a result, a larger number of floes can be treated in comparison with discrete element models. The ice interaction forces is formulated from the momentum conservation in the collisions of floes in a bunch and between the bunches. The movement of floes is calculated in combination with water flow using a multi-layer model to express the surface flow more accurately. Some computations using DMDF model were made. Computations for simplified ocean conditions showed some characteristics of the movement of floes around an ocean structure. Simulation results were also compared with the circulating water channel experiments. The DMDF predicted the circulating water channel drift tests quite closely.
