To make the present theory applicable to ice floes used in model tests, we request the typical length of an ice floe and the ship length satisfy the following relation (1) ε = L i / L s ≪ 1 where L ...
- Ship resistance when operating in floating ice floes: A combined CFD ...Importing the ice floes is achieved by an array-injection method. The simulation first runs for a certain time without sea ice to allow the fluid domain to achieve a steady-state, i.e. when the ship wake has become stable. Subsequently, an array of ice floes is injected into the computational domain near the inlet boundary, as shown in Fig. 5 (a
- Level Set Discrete Element Method for modeling sea ice floesSea ice floes often undergo breakage, due to floe–floe collisions, wave-induced flexural stresses, or shear due to ocean currents and atmospheric winds [36], [37], [38]. Existing theory cannot account for all these different breakage mechanisms, particularly in the marginal ice zone.
- Ice Floe - an overview | ScienceDirect TopicsA ship–ice floes–fluid coupling interaction was simulated embedding the DEM within the framework of the STAR-CCM+ software, where fluid solutions are solved using the traditional computational fluid dynamics (CFD) model of a ship proceeding in open water, and an array-inject coupling method was used to simulate ice floes cover the water ...
- Response of small sea ice floes in regular waves: A comparison of ...In order to further understand kinematics of ice floes in water waves, McGovern and Bai (2014a) conducted an experiment in a wave flume to investigate in detail the kinematic and dynamic response of ice floes, their drift velocity, the influence of body geometry, thickness and other parameters. They concluded that the ice floe's motion can be ...
