Résumé

Ice slurry is an energy-intensive secondary fluid, which may play an important role in various cooling purposes. From the system design perspective, it is of great importance to obtain detailed information of the ice slurry flow. A quantification of the complex two-phase flow characteristic is difficult due to the heterogeneous ice slurry flow. The paper includes the theoretical analysis of the ice slurry behaviour with different ice particle conditions (concentration, size) considering pressure drop and agglomeration. In addition to the mathematical model analyses of all important balance equations and other sub-equations (granular properties, phase interactions), various parameters influencing the behaviour of the ice slurry are considered. The CFD software has been successfully used to simulate the application of phase change material (PCM) in different technical applications, including cooling and air conditioning technologies. Based on the kinetic theory of granular flow, the ice slurry flow is described with and without consideration of melting. The Eulerian model provides granular properties and phase interaction parameters for the liquid-particle flow (ice slurry) to investigate particle collisions, drag, lift and turbulence dispersion. The numerical results were in good agreement with the experimental data from the literature.
