Modelling and Simulation of Ice/Snow Melting
A moving boundary problem, the so-called Stefan Problem, for the melting of ice is set up, then solved numerically using Matlab. Thereby curves for the position of the boundary between ice and water are produced. From these curves the melting time for a given layer thickness of ice/snow can be found. Furthermore, such curves are also presented when salt is added to the ice. It is seen that the ...
متن کاملNumerical and Experimental Analysis of Ice Melting in Water
The numerical simulation of ice melting in water considering temperature-dependent material properties and phase-change effects is proposed in this work. The governing differential equations (continuity, linear momentum and energy) are spatially discretized within the finite element method together with a implicit Euler scheme for the time derivatives. The melting of ice initially at –4.3 ºC an...
متن کاملSnow densification during rain
Observations and measurements indicate rain often has a major impact on snow slope stability. Measurements to investigate the effects of wetting of low density, alpine snow were made at Snoqualmie Pass, WA, USA. Results indicate that on first wetting, the densification rate can increase by three orders of magnitude. This initial burst of densification occurs independently of the gravitational l...
متن کاملSea ice, rain-on-snow and tundra reindeer nomadism in Arctic Russia
Sea ice loss is accelerating in the Barents and Kara Seas (BKS). Assessing potential linkages between sea ice retreat/thinning and the region's ancient and unique social-ecological systems is a pressing task. Tundra nomadism remains a vitally important livelihood for indigenous Nenets and their large reindeer herds. Warming summer air temperatures have been linked to more frequent and sustained...
متن کاملWidespread Albedo Decreasing and Induced Melting of Himalayan Snow and Ice in the Early 21st Century
BACKGROUND The widely distributed glaciers in the greater Himalayan region have generally experienced rapid shrinkage since the 1850s. As invaluable sources of water and because of their scarcity, these glaciers are extremely important. Beginning in the twenty-first century, new methods have been applied to measure the mass budget of these glaciers. Investigations have shown that the albedo is ...
