Bookmark or Share- A theoretical investigation of ship ice resistance in waters covered ...Comparison with experimental tests. It is lucky that Sawamura (2015) presented very good and clearly recorded model tests to measure ship resistance in ice-floe covered water. The ship model length is L = 1.5 m, width B = 0.3 m and ice thickness h = 0.01 m. All ice floes are circular with radius R = 0.05 m.
- Ship resistance when operating in floating ice floes: A combined CFD ...Ice-floe resistance in different-sized floes (floe diameters of [4] globally scaled by a factor), obtained when Fr = 0.15 and h = 0.02 m. The influence of ice thickness on the resistance is studied by varying h while keeping other parameters constant. Fig. 17 presents the ice resistance when h = 0.004–0.02 m, and for C = 40% and 60%.
- 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 ...
- Level Set Discrete Element Method for modeling sea ice floesFor LS-ICE we couple LS-DEM with a thermodynamic model of the ocean, to test the sea ice model’s behavior in summer Arctic-like conditions. This involves the evolution of a relatively packed field of sea ice floes (∼ 80% concentration) into a domain practically devoid of ice, within the course of 1–2 months.
- Experimental study of ship resistance in artificial ice floesSome interesting phenomena such as different ice floe rotating and attaching are observed. In this paper, a model-scale ship towing experiment is conducted to investigate the ship resistance in small ice floes. Instead of using refrigerated model ice, artificial ice floes made of Polypropylene (PP) is used in the tests based on the assumption ...
