Growth models of pure supercooled materials.

For a pure material, the dynamics of the growth of one phase in a supercooled other phase for the case of a shallow temperature quench is traditionally understood via a kinetic thermal diffusion equation model or a quasistatic Laplace equation model, if order-parameter details can be neglected. In the quasistatic model, the interfacial boundary temperature T(R) is equal to the phase transition ...

Molecular dynamics simulation of ice growth from supercooled pure water and from salt solution

The kinetics of ice growth on the prismatic and basal planes is studied by molecular dynamics simulations. The time evolution of two systems has been investigated. In one a slab of ice is initially in contact with supercooled water, while in the second the ice is in contact with a supercooled salt solution. The simulations were done at a temperature below the eutectic temperature, and complete ...

Dendritic Growth with Fluid Flow in Pure Materials

We study the growth of single dendrites from a small initial seed in an undercooled melt in the presence of a forced flow. Three-dimensional models are constructed, in which the solidification is computed using an adaptive finite element mesh and a phase-field method. We compare our calculations with available theories and experiments, and conclude that there are significant open questions rema...

Slow dynamics of supercooled water confined in nanoporous silica materials

We review our incoherent quasielastic neutron scattering (QENS) studies of the dynamics of supercooled water confined in nanoporous silica materials. QENS data were analysed by using the relaxing cage model (RCM) previously developed by us. We first use molecular dynamics (MD) simulation of the extended simple point charge model (SPC/E) for bulk supercooled water to establish the validity of th...

Thermodynamics of coarse-grained models of supercooled liquids.

In recent papers, we have argued that kinetically constrained coarse-grained models can be applied to understand dynamic properties of glass-forming materials, and we have used this approach in various applications that appear to validate this view. In one such paper [J. P. Garrahan and D. Chandler, Proc. Natl. Acad. Sci. U.S.A. 100, 9710 (2003)], among other things we argued that this approach...
