Abstract

The solidification process involved in ice slurry generation is accompanied by multiphase convection of liquid and solid phases. In this article, ice slurry generation in an inclined rectangular cavity has been investigated numerically and experimentally. The ice slurry is generated by freezing a hypereutectic aqueous ammonium chloride (H2O + NH4Cl) solution from one side of the cavity. In the numerical study, a validated macroscopic model, that consider solidification, multiphase convective flow, interfacial drag and particle sedimentation, is used to analyse the transport phenomena during ice slurry generation. The model predicts flow field, temperature, species and solid fraction distributions. In the experimental study, particle image velocimetry has been used for in situ study of the flow and the solidified and mushy zone thickness during solidification. The thermal history in the cavity at selected strategic locations is recorded by T-type thermocouples. The validation of the model and experimental and numerical results of evolution of solid fraction, temperature profile, multiphase velocity field and mass of ice slurry produced have been discussed.
