An experimental apparatus was developed to investigate the supercooling phenomenon of water inside cylindrical capsules used for a cold storage process. The coolant is a water-alcohol mixture controlled by a constant ...

An experimental device was developed to study dendritic ice growth in supercooled water inside cylindrical capsules. The capsule materials investigated were acrylic, PVC (polyvinyl chloride), bronze and aluminum. The ...

The freezing point and supercooling process are discussed for their impact on the traditional Andean freeze-dried potatoes called chuño. The freezing point depends on potato species, but typically it is slightly below zero ...

A key point to understand the glass transition is the relationship between structural and dynamic behavior experienced by a glass former when it approaches Tg. In this work, the relaxation in a simple bead-spring polymer ...

We study the supercooled one-phase Stefan problem for a semi-infinite material with temperature-dependent thermal conductivity at the fixed face x=0. We obtain sufficient conditions for data in order to have existence of ...

We study the specific heat of a model supercooled liquid confined in a spherical cavity with amorphous boundary conditions. We find the equilibrium specic heat has a cavity-size-dependent peak as a function of temperature. ...

By means of molecular-dynamics simulations we firmly establish the long-awaited existence of strong correlations between structure and dynamics for a glass-forming system: supercooled water. We find molecules with similar ...

We consider a supercooled one-dimensional Stefan problem with a Neumann boundary condition and a variable thermal diffusivity. We establish a necessary and sufficient condition for the heat flux at the fixed face x = 0, ...

The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...
