Journal of Ocean Engineering and ScienceDifferent from the existing CFD-DEM models in which the ship remains stationary, a CFD-DEM model with the ship in forward motion is proposed in this paper to simulate the process of a ship sailing across pack ice area at a forward speed under different ...

A bonded discrete element method for modeling ship–ice interactions in broken and unbroken sea ice fields [PDF]
Computational Particle Mechanics, 2019 This work investigates the failure patterns of ice cakes and floe-icewhen loaded by amoving and sloping structure (ice-breaking ships and cones). In the paper, we introduce the most frequently encountered ice infested scenarios, the main characteristics of ice-breaking ships and the predicted failure modes of floe-ice depending on the loading ...

Distribution characteristics of polar ship ice pressure in pack ice channel
Zhongguo Jianchuan YanjiuObjectiveIn order to study the distribution of ship ice pressure during the interaction between an icebreaker and pack ice, a numerical simulation analysis is carried out for polar ships in pack ice channels.

Numerical investigations of ship–ice interaction and maneuvering performance in level ice
Cold Regions Science and Technology, 2016 AbstractThis paper presents a solution to the ship–ice interaction problem solved in the time domain by a combined method involving numerical simulations and semi-empirical formula. The breaking process of an intact level ice by an advancing ice breaker has been investigated by a 2D numerical method.

Dipolar Interactions and Origin of Spin Ice in Ising Pyrochlore Magnets
, 2000 Recent experiments suggest that the Ising pyrochlore magnets ${\rm Ho_{2}Ti_{2}O_{7}}$ and ${\rm Dy_{2}Ti_{2}O_{7}}$ display qualitative properties of the spin ice model proposed by Harris {\it et al.} \prl {\bf 79}, 2554 (1997).

Multi‐Omic Profiling Reveals Immune Cell Priming Signature Linked to Lupus Prognosis
Arthritis &Rheumatology, EarlyView.Objective Systemic lupus erythematosus (SLE) is a multiorgan disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.
