A Numerical Prediction of the Resistance of Bulk Carriers in Brash Ice Channels

Journal of Marine Science and Engineering, 2023
Ship resistance increases significantly when navigating a brash ice channel. In this study, the numerical method is applied to predict the full-scale ship resistance of bulk carriers in brash ice channels.

Research on self-propulsion simulation of a polar ship in a brash ice channel based on body force model

International Journal of Naval Architecture and Ocean Engineering, 2023
Main engine power prediction is important for polar ships operating in brash ice channels, which is one of the most important concerns of shipowners. Self-propulsion simulation is an efficient method to predict the developed power.

A CFD-DEM-FEM coupling method for the ice-induced fatigue damage assessment of ships in brash ice channels [PDF]

Frontiers in Marine Science
Polar transport ships frequently traverse in the brash ice channel opened by icebreakers. Although the substantial ice resistance caused by direct collisions with the level ice is avoided, the hull still encounters collisions with the brash ice, leading ...

Numerical simulation of an ice-strengthened bulk carrier in brash ice channel [PDF]

Ocean Engineering, 2020
In this paper, the CFD-DEM coupling numerical method was applied to study the ship resistance of a certain type of ice-strengthened Panama bulk carrier in the brash ice channel. The ship-water interaction is established under Euler framework, and the ship-ice interaction is realized by means of the DEM method under Lagrange framework.

Resistance Performance of a Ship in Model-Scaled Brash Ice Fields Using CFD and DEM Coupling Model

Frontiers in Energy Research, 2022
The brash ice channel formed with icebreaker navigation is a normal working scenario for ice-going vessels. Therefore, it is necessary to study brash ice resistance in this condition.

Quantifying flow and stress in ice mélange, the world's largest granular material. [PDF]

Proc Natl Acad Sci U S A, 2018
Tidewater glacier fjords are often filled with a collection of calved icebergs, brash ice, and sea ice. For glaciers with high calving rates, this “m ́elange” of ice can be jam-packed, so that the flow of ice fragments is mostly determined by ...

The Precise Structures and Stereochemistry of Trihydroxy-linoleates Esterified in Human and Porcine Epidermis and Their Significance in Skin Barrier Function: IMPLICATION OF AN EPOXIDE HYDROLASE IN THE TRANSFORMATIONS OF LINOLEATE. [PDF]

J Biol Chem, 2016
Creation of an intact skin water barrier, a prerequisite for life on dry land, requires the lipoxygenase-catalyzed oxidation of the essential fatty acid linoleate, which is esterified to the ω-hydroxyl of an epidermis-specific ceramide.
