Cristallisation de coulis de glace basée sur une modélisation à changement de phase cinétique.

Ice slurry crystallisation based on a kinetic phase change modelisation.


Most crystallization models for ice slurries are based on approaches of thermodynamic equilibrium. This paper presents results of simulation grounded on a global Nakamura type kinetics coupled with the 1D nonlinear heat equation, another way to model the phase change. The model takes into account the energy needed at the different steps of the transformation, from nucleation to crystal growth. The work focuses on the study of the ice slurry crystallisation using kinetic tools integrating the temperature glide for mixtures (i.e., crystallisation equilibrium temperature Tf depends on residual fluid's solute concentration). The phenomena of transfers relative to the experimental device are determined at first, and then parameters of kinetic function of crystallisation are identified for pure water samples and for water-mono propylene glycol (MPG) mixtures (15% MPG mass fraction). The authors used an inverse method implemented with a code of genetic algorithm.
