High-pressure shift freezing. Part 2. Modeling of freezing times for a finite cylindrical model

A comprehensive vision of the heat transfer process involved in high-pressu re shift freezing (HPSF) is shown in comparison to the process at atmospher ic pressure. In addition, a mathematical model to predict the freezing time s is presented. This model takes into consideration the dependence of the t hermophysical properties relating to temperature and pressure and the super cooling reached by liquid water at atmospheric pressure after adiabatic exp ansion in the HPSF process. Experimental and theoretical data appear to agr ee.
