Abstract

To complete the deployment of the ice slurry technology using the supercooling water, modelling and design tools for the scalability of crystallizers are required. These tools may ensure a controlled and reliable operation of crystallizers, avoiding upstream ice prop-agation and exergetic losses, and high-efficiency supercooling release. To achieve this, ModIceCrys aims to develop a CFD-crystallization tool for modelling the ice crystallization process coupled with supercooled water flows. As a first step, the ice crystallization processes in supercooling water will be numerically investigated using the population balance model to obtain a stand-alone crystal growth model in non-flow conditions. Thereafter, a coupled fluid flow and the above-mentioned crystal growth model will be coupled by means of CFD in order to understand the fun-damentals of ice growth and its interaction within supercooling water flows. To conclude, the validation of the previous CFD-crystallization model via diverse non-intrusive quantitative flow visualization techniques, such as Particle Image Velocimetry (PIV) and Backlight Shadow Imaging (BIS), is foreseen.
