... will involve developing a large table of coefficients based on the video image and corresponding force/moment data analyses. A GUI-based software is developed to synchronize and analyze the video data in a semi-automatic fashion. This approach is novel and hence poses high risk as it is dependent upon two...

... for ship-ice interactions, which could lead to significant differences in the prediction of global ice loads on ships. In this work, an improved added mass model has been developed based on numerical results and existing analytical models. Added mass coefficients of three ice-going ships, CCGS Amundsen...

..., a virtual disc model for the propeller action is selected. Then, a simple sensitivity analysis on the ice friction coefficient was carried out to verify if the friction model is working appropriately. CFD-DEM simulation provides a promising result showing a similar ice jamming and pileup pattern...

The results also support the idea that downward-breaking cones correspond to lower horizontal forces than those acting on upward- breaking cones. Concerning ice sheet...
