Molecular Structure of Deeply Super-cooled Water

Hydration-dependent dynamics of deeply cooled water under strong confinement.

We have measured the hydration-level dependence of the single-particle dynamics of water confined in the ordered mesoporous silica MCM-41. The dynamic crossover observed at full hydration is absent at monolayer hydration. The monolayer dynamics are significantly slower than those of water in a fully hydrated pore at ambient temperatures. At low temperatures, the opposite is found to be true. Th...

Effect of Super - Cooled Water Droplet Characteristics on Fan Rotor - Ice Accretion

This paper presents a methodology for numerical simulations of super-cooled three-dimensional (3-D) water droplet trajectories through aeroengine rotating machinery that includes the effect of energy exchange between the droplets and flow. The governing equations for both flow and droplets are formulated and solved within the reference frame of rotating blades. A Eulerian-Lagrangian approach is...

The role of the isothermal bulk modulus in the molecular dynamics of super-cooled liquids.

Elastic models imply that the energy expended for a flow event in ultra-viscous matter coincides with the elastic work required for deforming and re-arranging the environment of the moving entity. This is quite promising for explaining the strong non-Arrhenius behavior of dynamic quantities of fragile super-cooled liquids. We argue that the activation volume obtained from dielectric relaxation ...

An Evaporative Style for Dynamic Ice-Slurry Producing with Super-Cooled Water

Ice-slurry is an ideal form of ice product for ice-storage, which is an effective measure to save energy. The conventional producing method using super-cooled water suffers the troubles of instability and heavy dependence on electronic power. We propose a novel method to improve that: spraying water is super-cooled by evaporating in a chamber where the air is of low humidity and low wet bulb te...
