Modern ice-going merchant ships have been customised for operating in ice and open water. The current model tests granting merchant ships Finnish-Swedish Ice Class may face challenges from the effect of hydrodynamics on the brash icebreaking process. Numerical simulations as alternatives for calculating ice resistance have shown their potential to assist model tests on ice performance prediction. This paper first reviews previous studies on numerical simulations of ships in a brash ice channel. Discrete element method (DEM) of modelling brash ice has become outstanding among other numerical methods, such as physics engine, finite element method and smoothed particle hydrodynamics. Coupling computational fluid mechanics (CFD) with DEM for ship-brash ice channel application have mainly been implemented in commercial software, but accessibility of the software is limited by the significant cost of license. This paper summaries key techniques of DEM, CFD and coupling methods related to the application in model scale and full scale based on open-source software platforms.
