Diffusion and Relaxation Phenomena in Ice

The Journal of Chemical Physics, 1969
The underlying mechanisms of several rate processes in ice are examined through cross comparisons of the processes with each other and with experimental observations. The assumption that the migration of orientational defects (Bjerrum faults) is the common origin of dielectric and elastic relaxation leads to a predicted ratio of dielectric-to-elastic ...

Freezing phenomena in ice–water systems

Energy Conversion and Management, 2002
The characteristics of solidification and melting are reviewed. The properties of water and ice and the phase diagram of water are discussed with special emphasis on ice density. A concise account of the freezing process and the Stefan problem is presented.

Cratering phenomena on aircraft anti-icing films

Journal of Aircraft, 1996
This article reports on a study of cratering effects in thin anti-icing films designed to protect aircraft surfaces from snow and ice accumulation while the aircraft is on the ground awaiting takeoff. These fluids primarily consist of a glycol used as a freezing point depressant, water, and to a small extent thickening and wetting agents.

Some surface phenomena of ice

Journal of Colloid and Interface Science, 1967
Abstract Two new phenomena are described which would indicate directly two mechanisms of mass transfer along an ice surface. One is the neck formation observed between an ice sphere and a plane placed cose to but not in contact with it in an ice-saturated atmosphere.

Modeling transport phenomena of ice slurry in an ice forming unit

International Journal of Refrigeration, 2016
In this article, multiphase convective and solidification transport phenomena of ice slurry is investigated by developing a one-domain macroscopic model to simulate its formation in a rectangular ice forming unit. Convection, sedimentation, interfacial drag, permeability, remelting and viscosity variations are incorporated into this model through the ...

Snow‐and‐ice phenomena in the polar urals

Polar Geography and Geology, 1989
Abstract Long‐term studies carried out in the test basin of the Bol'shaya Khadata River have allowed the authors to describe the complex of glacio‐nival phenomena typical of the rock tundra zone of the Polar Urals. It was found that the winters are characterized by snow drifting, which results in redistribution of snow at the macro‐ and especially the ...

Ice release phenomena modelled by Finite Element models

AIAA Modeling and Simulation Technologies Conference, 2016
The main purpose of this paper is to present an ice release fracture model taking into account the cohesive phenomena. Developed on the basis of the standard finite element method implemented in ANSYS software, the test-case consists in an iced cantilever beam (structurally representative of an engine rotating component) excited by applying a vibrating

Multiscale Models of Sea Ice Phenomena

2019
Sea ice can be viewed as a composite material over multiple scales. On the smallest scale, sea ice is viewed as a two-phase composite of ice and brine. On the mesoscale, one may consider pancake ice and slush as a viscoelastic composite. On the larger scale, one may consider the mix of ice floes and water.
