Ice accretion compositions in ice crystal icing
International Journal of Heat and Mass Transfer, 2023 Ice crystal icing is a major hazard in aviation from the perspectives of aerodynamic deterioration, flight safety and operability. To counter this challenge, existing ice prediction tools require more accurate modeling of sticking efficiency of glaciated ice crystals on heated substrates. As part of the present study, icing wind tunnel experiments have

Ice swimming – ‘Ice Mile’ and ‘1 km Ice event’ [PDF]
BMC Sports Science, Medicine and Rehabilitation, 2015 Background: Ice swimming for 1 mile and 1 km is a new discipline in open-water swimming since 2009. This study examined female and male performances in swimming 1 mile (‘Ice Mile’) and 1 km (‘1 km Ice event’) in water of 5 °C or colder between 2009 and 2015 with the hypothesis that women would be faster than men. Methods: Between 2009 and 2015, 113 men

Physical Review Letters, 2003 We report results from molecular dynamics simulations of water under confinement and at ambient conditions that predict a first-order freezing transition from a monolayer of liquid water to a monolayer of ice induced by increasing the distance between the confining parallel plates. Since a slab geometry is incompatible with a tetrahedral arrangement of

Raman Investigation of the Ice Ic–Ice Ih Transformation [PDF]
The Journal of Physical Chemistry C, 2020 Among the many ice polymorphs, ice I, that is present in nature at ambient pressure, occurs with two different structures, i.e. the stable hexagonal (Ih) or the metastable cubic (Ic) one.

Journal of Geophysical Research: Solid Earth, 2012 New measurements have been made of the friction coefficient of freshwater polycrystalline ice sliding slowly (5 × 10−8 to 1 × 10−3 m s−1) upon itself at temperatures from 98 to 263 K under low normal stresses (≤98 kPa). Sliding obeys Coulomb’s law: the shear stress is directly proportional to the normal stress across the interface, while cohesion ...

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]
, 2004 Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

IC-Colorings and IC-Indices of graphs
Discrete Mathematics, 2005 The IC-index of a connected graph \(G\) is defined as the largest integer \(k\) with the following property: It is possible to assign positive integer labels to the vertices of \(G\) so that the labels sum to \(k\) and for any \(i=1,2,\dots,k-1\), there is a connected subgraph of \(G\) whose labels sum to \(i\).

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]
, 2015 Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.
