Kinetics of Phase Transitions Induced by Shock-Wave Loading in Ice

Abstract

indicates a series of phase transitions in ice and gives evidence of the important role the kinetics plays in the process of dynamic phase transformations in ice. In order to model multiple phase changes in ice subjected to impulsive loading, thermodynamic equations of state of ices Ih, III, V, and VI and liquid water are used in the pressure range 0-2100 MPa and the temperature range 230-350 K. A kinetic model is presented that makes it possible to describe quantitatively a complex picture of the phase transitions in ice. The results of computer simulations of shock-wave loading of ice are consistent with the available experimental data.

Thermodynamics of ice at high pressures and low temperatures

“…2); this deviation is due to a complex dynamic response of temperate ice to shock compression at po600 MPa [14]. A detailed description of the behavior of dynamically compressed ice at high pressures is beyond the scope of this paper; a kinetic model of multiple phase transitions in ice induced by shock-wave loading can be found elsewhere [16][17][18].…”

“…The thermodynamics of ices and their equations-of-state (EOS) are of fundamental importance for many areas of science and technology, in particular, glaciology [6], oceanography [7], space and planetary science [8][9][10][11], physics of shock compression of water substance [12][13][14][15][16][17][18], high-pressure food processing [19][20][21][22][23] and low-temperature preservation of biological materials [24].…”

The initial responses of hot liquid water released under low atmospheric pressures: Experimental insights

“…The experiments of Sears and Chittenden (2005) were designed to investigate the mass loss rate at a range of brine temperatures from 0°C to À26.0°C, where the liquid brine was exposed to an atmosphere and was not covered by ice. Chittenden et al (2008) studied ice sublimation rates under forced convection at martian atmospheric pressure and a temperature of c. À15°C, finding Equilibrium water phase diagram from absolute zero to 1000 K, and 0.1 Pa to 10 12 Pa, modified from Tchijov et al (1997Tchijov et al ( , 2008. Solid lines are phase boundaries at which two phases can coexist.…”
